- DoktorRob, on 12/30/2008, -1/+109This is the same type of radiation beam that I put my skull in front of for two months to treat a skull base tumor near my pituitary gland and optic nerves. What you don't see is the cyclotron that produces such a proton beam (think very miniature version of the LHC (just room sized not miles across)). I was treated in Houston at MD Anderson's Proton Therapy Center (a newer facility than the one in the video). The only time I actually had any physical sense (other than some localized hair loss) of the proton beam was when it was being directed through my nasal passage from the rear of my skull. I could smell the ozone as the protons ionized the air I was breathing out. The doctors were curiously surprised by my reports of this.
I'm fascinated by this video, thanks for digging it.
Also, I work in digital imaging for NASA and we see this type of damage to CCDs in the cameras the astronauts use on the shuttle and space station. But we never get to see it as it happens. - rkyle, on 12/30/2008, -1/+104Thanks for giving me cancer over YouTube. Much appreciated.
- Neworab, on 12/30/2008, -1/+34I was scared for the camera
- JousterL, on 12/30/2008, -4/+36That was actually a fun watch.
- DoktorRob, on 12/30/2008, -0/+31Yes I am, thank you. And I credit proton radiation therapy along with a good team of doctors and surgeons at M.D. Anderson.
- o0dhacker0o, on 12/30/2008, -1/+27Anyone else hoping the camera would erupt in flames at some point in the video?
- Someguy101, on 02/19/2009, -0/+22Dude... hope you're ok now
- kerbe6, on 12/30/2008, -0/+19"Are they particles being reflected somehow by the webcam body or electronics?"
Yes. - thatsgoodkarma, on 12/30/2008, -3/+18Physics is more interesting than this comment.
- Loshunter, on 12/30/2008, -2/+16That's a lot of fancy equipment to simulate the static snow I get then I unplug the cable to my tv!
- superkendall, on 12/30/2008, -1/+15So here's a simple question - why are there particles striking the CCD at a steep angle, if the beam is pointed directly at the CCD? Are they particles being reflected somehow by the webcam body or electronics?
- dafragsta, on 12/31/2008, -0/+12Dugg for a real NASA employee on Digg shooting tumors with particle accelerators.
- doublefelix, on 12/30/2008, -2/+11Unexpectedly dramatic.
- Phych, on 12/30/2008, -0/+8Apparently you can't wage destruction without your laptop...that and wifi reaches the forest.
- , on 12/30/2008, -1/+7I couldn't see any Particle Beams thanks to all that static.
- Jhiaxuz, on 12/30/2008, -0/+6He'd turn into a mutated hybrid nerd who can pick up chicks.
- oderdigg, on 12/30/2008, -1/+6NASA HMO.. best money can buy
- Aadain, on 12/30/2008, -0/+5You know, air does consist of particles & atoms & molecules which do deflect/reflect particles. If the space between the emitter & webcam had been 100% vacuum, the hits would (most likely) all at the center of the CCD.
- glucoseboy, on 12/30/2008, -0/+4Fascinating. I love science!
- Murdats, on 12/31/2008, -0/+4they don't need to pass through the body, the CCD is the thing that captures images, it reacts to things like photons, if light can reach it so can protons.
- jeexbit, on 12/30/2008, -1/+5My god, it's full of stars...
- CLAPYRHANDS, on 12/31/2008, -0/+3Two words: Particle Man.
- mstachiw, on 12/30/2008, -1/+4figures... give a particle beam the internet and it immediately dims the lights and shoots its particles all over a webcam. have you no mercy internet!?!
- Murdats, on 12/31/2008, -0/+2you realise our entire civilisation is built on science, science drives economies to a massive level, science does so much to improve everything, yet it gets a pittance, we give it a small fraction of our budget despite all that science provides.
- rob2oo4, on 12/30/2008, -0/+2Reminded me of the scene from Willy Wonka
- lukemit, on 12/30/2008, -0/+2So, could someone explain to me why this is so cool?
- Spetz, on 12/31/2008, -0/+2I doubt the webcam will have a CCD in it. CCDs are generally too expensive for a low cost consumer application like a webcam so it will probably be a CMOS image sensor.
The permanent damage created to the image sensor will probably be in the form of the E-centre defect complex which is comprised of a silicon divacancy (created by the energetic proton) and a phosphorus/arsenic impurity. It's quite cool to see this happen in real time. - louiebaur, on 12/30/2008, -1/+3Agreed, good video
- inactive, on 12/31/2008, -0/+1The angled particles look like comets and the others are just the stars.
- inactive, on 12/31/2008, -0/+1because destroying a ccd on a more expensive webcam makes sense, when you can achieve the same exact effect on a basically disposable one? moron.
- manogamez, on 12/31/2008, -0/+1I hope you got well.
Cool story. - inactive, on 12/31/2008, -0/+1..and suddenly I'm no longer concerned about the LHC. Those little particle dudes look harmless enough.
- Murdats, on 12/31/2008, -0/+1except for in the LHC they bored through quite a lot of concrete before reaching that harmless level.
- inactive, on 12/31/2008, -0/+1new high tech means of looking into the girls locker room.
- JimmyTruth, on 12/30/2008, -2/+3I had the feeling of standing in front of a firing squad before the beam was activated.
Awesome video by the way. In the immortal words of the Bill Nye the Science Guy theme song.. "Science Rules." - inactive, on 12/30/2008, -0/+1I'm disappointed! The camera didn't start glowing red or melt or anything.
Joking aside, that was really cool. I was expecting to see something more like a bright light coming from the projector, like a laser. - mattofasia, on 12/30/2008, -0/+1It needs to be said:
"I for one, welcome our new particle beam overlords."
There, now thats done. - crossmr, on 12/31/2008, -0/+1Was that caused by the equipment or youtube? it looks similar to most of the youtube videos I see.
- Metasquares, on 12/31/2008, -0/+1I was surprised it took such little damage.
- tehWyman, on 08/19/2009, -0/+1Damn I love some of the life stories on Digg. Probably a big part of the reason I read through the comments.
Hope everything stays alright with your health. - danger127, on 12/31/2008, -0/+1You diggers seem to know about science: When it says the beam crossed at a high angle, is the Compton Scattering? Like when the proton passed through the lens, and Compton scattered at the new angle that the CCD picked up? I know that once a particle undergoes scattering it looses energy, but since it's hitting more CCDs that could be why it looks brighter.
- danger127, on 01/10/2009, -0/+1I was trying to confirm my suspicion *****
- danger127, on 12/31/2008, -0/+1not any more than the protons you are surrounded by right now
- 13373h4X0r, on 01/01/2009, -0/+1Web camera: "Owwwwwwwww!!! It hurts!!!!"
- rebotfc, on 01/19/2009, -0/+11.21 JIGGAWATTS?
- Yage2006, on 12/30/2008, -0/+1That sure is a long step down from LHC.
- m4csrgh3yk3v, on 01/01/2009, -0/+1I'm a little skeptical about this vid, unless someone tells me that the protons were at hundreds of keV.
The collisional mean free path of the air would be very short for low energy protons at 1 atm. There would be no beam, it would be like running a hose under water. The only way around it would be high energy protons. - yaazz, on 12/31/2008, -0/+1Only because I was sure something was going to pop out and scream!!
- wiitarded666, on 12/30/2008, -1/+2same... i thought i was alone i had my had on the volume just incase
- kerouac906, on 12/31/2008, -0/+1I'm suing for the dead pixel on my monitor.
