Since 1990, doctors have been regularly treating cancer patients using proton beams, which work similarly to radiation. Proton therapy is more precise, however, causing less harm to healthy surrounding tissues. Unfortunately, generating a proton beam requires a particle-accelerator facility that’s the size of an airplane hangar and costs more than $100 million to build. Thus, proton-beam therapy remains a rarity, with only 37 working facilities worldwide, 10 of which are located in the U.S. Just 10,000 people were treated last year, less than 5 percent of suitable patients.
Now scientists at the Compact Particle Acceleration Corporation in Livermore, California, are developing a 13-foot-long particle accelerator that costs about $30 million. Most accelerators use large magnets to generate the electromagnetic field that pushes charged particles. The magnets require 10-foot-thick concrete shielding and bulky hardware. CPAC’s prototype creates the electromagnetic field with electric lines, which don’t require massive shielding or large additional equipment. The new accelerator could be commercially available as soon as 2015. (The numbers below will match you up to the location in the picture above.)
1. PROTON BEAM
Magnets in the kicker pull positively charged protons from hydrogen plasma made by a duoplasmatron. A deflecting magnet collects the stream into proton bundles, which then enter the injector, where a microwave field speeds the particles toward the acceleration chamber at up to five million mph.
2. LASER
At nearly the same time, a laser fires a light pulse, which splits into fiber-optic cables of various lengths.
3. ACCELERATION CHAMBER
As a bundle of protons enters the acceleration chamber, a light pulse hits the chamber’s first pair of electric lines, triggering the release of electrons. The resulting electromagnetic field propels the proton bundle forward. The light pulse triggers the electric lines in a wave, sequentially accelerating the proton bundle until it’s traveling at 335 million mph—or about half the speed of light.
4. CLOCK
The entire process is controlled by a clock, which directs magnets to turn on or off and the laser to fire.
5. ROBOTIC CHAIR
Moving a patient is easier than moving a 13-foot-long particle accelerator. A robotic chair maneuvers a strapped-in patient in front of the proton beam to target a tumor from different angles.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Honey, I shrunk your tumor??
That's awesome...
I am all for medical science and less for cosmic science. I want to see direct results for the benefit of humanity, verse wait around awhile for the trickle down technology to arrive elsewhere. And all the science that was develop for the stars was invented and produce on terra firma earth and not in space. We do not need space for a goal to advance in technology. We can apply a more direct approach to problems and not wait around for solutions. When it comes to these exotic devices at hospitals around the country, I like to see the hospitals get these units as free as possible, (yes paid by the tax payer), so doctors can use them more freely on patients if they do or do not have insurance, thereby increasing the quality of our health care and reducing our health insurance premiums over all.

Of course I propose any medical student that graduates from college with a GPA of 3.9 get his education paid for free by the Federal government and any part time course they take after that and Aces get paid free too. I want to entice the best to grow freely in medical science. We the community will win. When a college student graduates, they pass their bills on in their requested salary, so let’s reduces those college bills. The community wins again. Let the bright medical student be all they can be!
Second, I like to see any hospital that serves a community sees a certain number of people (a fair number would have to be decided by the government) get free electronics exotic devices free from the government, MRIs, X-ray Machines, Lasers, etc. If a person has no insurance doctors will not be hesitant to treat them with exotic devices. The cost of this to the hospital will not be passed on to those with insurance and increase the cost of health care. Let’s give doctors that serve many in hospitals all the tools they can so they can serve as many as possible, often!
Finally, let’s allow healthy insurance companies the ability to compete nationally, not just within the states! Let’s open up the playing field to be larger in capitalism. Health care and its cost affect us all!

@ Robot,
You can take your socialist ideas and shove them where the sum doesn't shine. The reason why we currently have a shortage of medical professionals is the overbearing federal and state regulation that already exists. Not to mention that doctors must cow-tow to the AMA and are not free to practice medicine as they see fit and their patients allow.
Your only intelligent remark was releasing restrictions on where an insurance company can sell health insurance. I feel that I should remind you or if you didn't already know, just tell you that the U.S. is the most indebted nation in the world at current with more than $50,000 in debt per man, woman, and child and this figure does not take into account the unfunded liabilities of medicare and social security. So your idea that gov't can just pay for all of this increased medical spending is a massive miscalculation on your part.
Lastly, I would like to warn you that people like myself do not take kindly to being told what to do and being forced pay for unconstitutional expenditures at the point of a gun. So far, we have been more than lenient and have tried to use our votes to circumvent your insanity and evoke change. When the majority of us find that this is no longer a viable option, we will not be so kind. There are limits to the actions of gov't and the actions of the individual. As soon as you start to use force and coercion against others, you have exceeded your bounds and the use of force to stop you is then authorized. You have been warned.

A bitter sweet outcome...
SgtB,
I applaud your freedom of speech and the democratic process. I am not a socialist. What my goal is to enhance the quality of healthcare simply, by an incentive of top notch educated health care professionals.
You do realize the cost to your insurance when you visit a hospital also covers those who do not pay health insurance. That annoys me; does it annoy you too? It also annoys me that some people are neglected state art advance medical treatments simply because they do not have health insurance. I have a hard time thinking one human being is better than another. Yes it is a complicated issue and I welcome your opinion SgtB.
You do realize most of you money in our life time will be spent in the last few months, keeping you or your love one alive using this exotic type medical devices. Now how you feel if all of sudden these device were given to the hospital for free and you did not have to suffer the expense of these devices, only to pay for the doctors and nurses themselves? What if the hospital institution themselves did not have to worry about the cost of these devices and were more free to use them. This increases the odds of them saving you or your love one by better and earlier diagnoses.
When you are close to death in life, it is a big windfall for the hospital, where as you could of given all your earned in life to your love ones. But as you prefer to call it socialism, the doctors win and you love ones loose.
Another nice thing of democracy is the fair playing field of capitalism, which is my other brain store to allow the health insurance companies to compete nationally.
Hey, I do not want socialism either. I am on your side. But just complaining about my propose solution does nothing; I encourage you to respond with a solutions of your own, sir.

SgtB,
You do realize I said give to the hospitals that serve the large QUANTITY of people, not making making the largest profit. I want to help the most caring, most serving hospital in your and mine community. And since they do have such a large and caring attitude, give them the tools to do their job, so we all benefit!

SgtB,
You do realize it was President Johnson that opens up the loop holes to siphon off the excess funds in our social security? You do realize it was the law makers that allow health care to run out of control? You do realize in 7 years these things go bankrupt? You do realize it was our government that loosens the laws with banking so more easy mortgages could be given to people of low credit, which cause inflation of housing and these people being what they are of low credit, bankrupt the system. And our government they bailed out the banks. The banks won coming and going. In 2005, my house new was worth 153k. I bought it in 2009 for 100k. Now 14 houses in my community are abandoning and my house is worth 43k. Those who lost their house now have worse credit and will be force to pay rent the rest of their lives. Mean while, my HOA still goes up, electric still goes up, health care still goes up, inflation goes up and gas prices too. The rich keep getting richer and the quantity of middle classes and poor are becoming poorer.
In the USA a gigantic amount of people lost their retirement and homes and they will have to pay gigantic amounts of money for health care in their old age they do not have, to end in suffering. But bankers got bonuses and stock holders made big profits!
When it comes to our future, more people will be poor and paying rent and giving everything they own when they become old and unhealthy. The rich will have wonderful health care and continue to be rich. We are not moving to a social state in this country, we are slowly moving to a cattle and slave state of exploitation by the rich!
I say all the exotic medical devices for hospitals should be paid by 1% rich. They spent their whole lives enjoying the benefits of the working class and them them selves having excellent health care. It seems only fair they give back in heath care, what society has given to them in a beautiful life!
Last, I believe ever Veterans Hospital should be the most advance state of the art hospital and we should do all we can for those who sacrifice themselves for our country!

Cool. After it becomes medicine, it will be a cool weapon to be feared.
@ Robot, The path to Hell is paved with good intentions. If you really feel so strongly about providing "exotic" medicines to the poor and old so that they may live a few more months, weeks, or days; then be my guest. But do it with your own money and not what you confiscate from others using the force of government. You say that you are not a socialist, yet you sound an awful lot like one.
It also appears that you missed the point altogether with social security. The social security trust fund has only ever invested in federal bonds since its' inception. And the first people to get social security benefits never paid into the system. So the entire system is a fraudulent Ponzi scheme of grand proportion. You see, a bond is never issued unless there is some debt to be financed. All of the "investments" in the social security trust fund have been used to pay the debt of the U.S. government. In 2018, the receipts and expenditures over at the soc. sec. office are expected to match and from that year on, we will either have to start borrowing from foreign nations or demanding higher taxes to continue to pay the benefits of this Ponzi scheme.
And these are the results of people like you who just want to keep grandma in her home and with food on her plate. I admire your goal, but the execution is the path to Hell. So you need to revise how you look at situations and how you can implement the change you want to see without committing theft and the destruction of a nation.
As for how I plan to help out, well, I'll start by taking care of my own family. If that means that grandma needs help paying for food, then I'll go buy her groceries. What I don't need is a gov't official at the end of the year confiscating my money that I could be using for that means and then redirecting it to Washington D.C. where it will have an enormous handling fee attached and then be spent unwisely on unimportant things like free cell phones for those in section 8 housing.
And about all those lost retirements... Did it ever occur to people of your generation that maybe, just maybe you should not rely on another to supply you with your retirement or insurance needs? I mean, exactly when does personal responsibility and covering your own ass come into your mind? Further, even if you only make poverty level wages your entire life, if you didn't have to pay 15% fica tax and you could invest that 15% of your income from 18 to 65, you would end up with ~ $800,000 to retire on. And if you are smart, you will work just a little longer and then live off of just the interest alone so that your retirement account doesn't deplete but in fact continually grows.
SgtB,
You call social security a ponzi scheme. You say I am going to hell and I am promoting socialism, both untrue. Yes you offer no positive solution of your own. Typical of people who cuss and offer violence, when rationality eludes them and control is all they are interested in.
Enough with insults; your just a distraction and time waster. Come back and offer some sort of solution. I do not offer the one and only solution. I like to see you and other POPSCI bloggers offer solutions. Perhaps in the combination of opinions and brainstorming a better way can be found within the confines of free speech and democracy. I find it most annoying only you and I speak about this subject. I am no authority and I believe solutions do exist!
Enough with the insults; propose solutions, sir, you or anyone!

SgtB,
Everyone fights for life at the tail end or they fight for their love ones. Remember all that money you saved all you life for your retirement and assets you acquire. You will sign a document at the hospital upon your death it goes to the Hospital business, its owners and stock owners, everything you did all your life.
I appreciate a single man that works hard and is exceptionally smart. I am speaking about exceptional doctors and medical people. I only offered them a free educational ride, since they work hard to get where they are and we the sick patient enjoy the benefits of their hard work. It seems like a win win situation. I appreciate the staff that saves my life or my love ones. I loathe giving my life time of hard work to a Hospital institution and helping the rich get richer.
Many poor low incoming people were given opportunity to fast and a house they could not afford. What they really need was to wait and prepare better and have better financial guidance for their future. Instead via the government making loose the mortgage laws, they would give an opportunity they were not prepared for. Now they out of a house and their credit rating went from poor to actual damage. They will spend the rest of their lives renting, maintaining the rich and never owing property of their own.
For the big players of this game, the banks and the law makers that supported them. Well the banks one when they sold high mortgages during a over inflated market. They bank CEOs one big bonus. The stock holders one on the rush of this market too. And when the banks were consider too big to fail, they were bailed out and continue to be more profitable. From the year 2005 to now, the gap of the rich to the middle class and poor is even wider with inflation.
Whatever money you have saved all your life for your retirement, it has less value as everything around you continues to go up as well as medical cost.
You manage to save for a retirement and all I get from you now is look down on me smugly. You do not even know my age and you referred to me as son. You assume too much on your part. You assume those who lost their retirements when a great many banks did fail were not hard working and intelligent people. You mind is in a box and you’re a smug condescending unsympathetic jerk, make large negative assumptions about poor people around you and offer no postive solutions.

I am living proof that this works. Had an acoustic neuroma treated in 1994 at the Harvard Cyclatron. In my case it worked by basically cauterizing the base of the tumor and cutting off blood supply. I was strapped into what looked like a dentist's chair that rotated on 7 axis. They shot the beam through a half mile tunnel through a brass dye the exact shape of the tumor. Pretty cool stuff.
