GoPro Ride Through an Electron Beam Irradiator at Full Beam Power [video]
- yencabulator 3y agoDoes it still count as "full beam power" if it's in a lead box? That means the full beam power did not reach the GoPro.
- wkat4242 3y agoI wonder what that thing is actually used for
- r2_pilot 3y agoIn this video, it's for examining calcite according to the description; I believe I've also seen similar devices used for making lichtenburg figures in acrylic.
- Ballas 3y agoYou might be correct on both counts: https://fusor.net/board/viewtopic.php?t=8666 https://fusor.net/board/viewtopic.php?t=8666 (I'm not sure if this is the same run, the link in my link seems to be dead)
- GordonS 3y agoI believe they are used to irradiate cannabis too (to kill mould & yeast) - electron-bean irradiation retains much more terpenes than gamma irradiation does!

- GordonS 3y agoYes, a lot of commercially grown cannabis is, unfortunately, irradiated. Different countries (abd different US states) have different laws about the amount of mould and yeast that are permitted on sold cannabis flowers (as well as other things, such as moisture content). The target is quite hard to meet got some markets, including the UK and EU. To get to the required levels, irradiation isn't necessary... but it's cheap and easy. I get the sense that it's often used because of poor growing practises, more than anything else. I can't speak for other countries, but in the UK most cannabis has until recently been gamma irradiated - which often led to practically terpless flower that smelt of damp hay. More recently, e-beam (electron-beam) irradiation has largely taken over - and it seems to be much, much kinder on terpenes! Honestly, most is now impossible to tell apart from non-irradiated flower. I don't have actual data, I'm afraid. There's a single paper talking about cannabinoid and terpene content of cannabis after gamma irradiation, which was paid for by Bedrocan - but I haven't found anything about how it compares to e-beam.

- chankstein38 3y agoI believe I was actually at this facility around the time this video was taken! I was there with a large group mixing scientists and others who were sending acrylic through it to make captured lightning/lightning sculptures/lichtenberg figures! It was a really cool experience! I met this guy there: https://www.capturedlightning.com/ https://www.capturedlightning.com/
- m463 3y agoThat seemed familiar - I have some shrunken coins: https://www.capturedlightning.com/frames/interesting1.html https://www.capturedlightning.com/frames/interesting1.html
- myself248 3y agoOne common use is cross-linking polymers. If you've ever used cable with XLPE insulation, it was initially extruded onto the wire as normal polyethylene, then spooled back and forth between drums passing under an e-beam system like this, to perform the cross-linking. It's phenomenally tough stuff after that; a lot of cars use XLPE (in its thinwall TXL spec) wiring.

- lordfrito 3y agoI never thought I'd see a Resonance Cascade, let alone create one.
- geocrasher 3y agoThat looks a lot like several levels of the first Portal. That conveyor system didn't run on GladOS, did it?
- proactivesvcs 3y agoHuh, so those factory and warehouse levels in Quake II were accurate? Stuff does just get ferried around on conveyor belts for seemingly no reason. Pleasing taste, some monsterism.
- Arrath 3y agoSeems safer than having a PhD push the sample into the electron beam with a trolley.
- perihelions 3y agoThe PhD's cheaper.
- csours 3y agoThe first grad student is cheaper. The lawsuit ... ehhh
- giantrobot 3y agoLawsuits require survivors. The implications are clear.
- toxik 3y agoThey’re waiting for you Gordon, in the test chamberrr...
- dylan604 3y agoBut no PhD would do physical labor. That's what undergrads, PhD candidates, or even the interns are for.
- dmd 3y agoAh, yes, no postdoc has ever been ground down by endless repetitive labor.
- 3y ago
- ein0p 3y agoI’m surprised it not only survived this, but also did not even stop filming.
- scaredginger 3y agoIt was shielded
- i80and 3y agoI wondered about that, but from the description: > GoPro is enclosed in a 3/8" thick lead pig with a 1/2" thick, 50% lead glass window. Additionally there is a 1/4" thick lead plate above the camera box to provide shielding from direct irradiation from the beam.
- animatethrow 3y agoAliens could plausibly sterilise earth from light years away using an electron beam, according to a great Kurzgesagt episode: https://www.youtube.com/watch?v=tybKnGZRwcU https://www.youtube.com/watch?v=tybKnGZRwcU An electron beam seems to be the stealthiest of the three extermination options, the other two being a star laser and antimatter "rods from God."
- FirmwareBurner 3y ago>An electron beam seems to be the stealthiest of the three extermination options Or they could just false flag a nuke strike and watch us sterilize ourselves.
- gridspy 3y agoA lot of effort is currently put into tracking missile launches and predicting ballistic trajectories. The goal is to give some warning if a nuclear strike is launched. It would be obvious if a strike came from an extraterrestrial source, there would be no terrestrial launch detection. In addition, such a attack is unlikely to succeed. It would take a long time to arrive on earth and by the time the result of the attack was known there could be angry Earthlings counterattacking.
- consumer451 3y ago> A lot of effort is currently put into tracking missile launches and predicting ballistic trajectories. The goal is to give some warning if a nuclear strike is launched. Less advanced nations such as North Korea and Pakistan have nukes. Do you think that their monitoring systems are really that good?
- gambiting 3y agoNo, but they won't destroy the earth with what they have - untold destruction of couple other nations, with millions dead and extreme humanitarian and economic catastrophe - sure, but not extinction of life on earth.

- cgijoe 3y agoSo... what would happen if you took a ride with it? Instant death? Painful death? Slow death over several days? I need details!
- indrora 3y agoSlow, painful death from radiation exposure. There's some well-documented cases of people getting Real Fucked Up from irradiation systems that weren't maintained. Plainly difficult has two good examples of these that were badly maintained and put people into the ground in lead-lined coffins: https://www.youtube.com/watch?v=8V4q59o_mjU https://www.youtube.com/watch?v=8V4q59o_mjU and https://www.youtube.com/watch?v=vDGN_Q_0jWI https://www.youtube.com/watch?v=vDGN_Q_0jWI
- Analemma_ 3y agoDepending on the voltage, you might die immediately from being electrocuted, or a few days later from radiation poisoning. The stories of the people who died from the Therac-25 machine are probably instructive: https://en.wikipedia.org/wiki/Therac-25#Radiation_overexposure_incidents https://en.wikipedia.org/wiki/Therac-25#Radiation_overexposu...
- jasonwatkinspdx 3y agoThere's a Russian Physicist that was in an accident where a proton beam went through his head: https://en.wikipedia.org/wiki/Anatoli_Bugorski https://en.wikipedia.org/wiki/Anatoli_Bugorski He lived but with some brain injury. I'm not sure what the differences in effect electrons vs protons and a focused vs diffuse beam would be though.
- acjohnson55 3y agoIf it happened after a series of humiliations and misfortunes, you would become a supervillain.
- chasil 3y agoIt already happened. "...the Therac-20, which could produce X-rays or electrons of up to 20 MeV. "This dual accelerator concept was applied to the Therac-20 and Therac-25, with the latter being much more compact, versatile, and easy to use. It was also more economical for a hospital to have a dual machine that could apply treatments of electrons and X-rays, instead of two machines. " https://en.m.wikipedia.org/wiki/Therac-25 https://en.m.wikipedia.org/wiki/Therac-25 This has been posted many times. https://news.ycombinator.com/item?id=38458448 https://news.ycombinator.com/item?id=38458448

- SomeoneFromCA 3y agoHa, now I see why I suddenly got it in my youtube recommendations.
- ethbr1 3y agoI didn't realize how much Valve mentally linked miniature rail cars, physics, and Half Life for me...
- sandworm101 3y agoLike the original Pirates of the Caribbean, but with science! Fyi, if you start seeing those little single-pixel stars in your VR headset, you have probably wandered out of the play area.
- conjecTech 3y agoDidn't expect to see a familiar face at the end! Andrew, if you're reading this, greetings from a fellow RoboJacket!
- omgJustTest 3y agoBlue light just before entry - very likely Cherenkov radiation. Apparently some phosphorescent materials or just electron-induced heating on the cart in front. White speckles are electrons !
- preisschild 3y agoCherenkov radiation only appears under water. In this case it is because the electrons ionize the air.
- omgJustTest 3y agoCherenkov exists in all media except vacuum. It is when electrons travel faster than speed of light in the media (in this case air). In vacuum they are limited by the speed of light. For example: https://www.mpi-hd.mpg.de/hfm/CosmicRay/ChLight/Cherenkov.html#:~:text=Charged%20particles%20moving%20through%20the,the%20direction%20of%20the%20particle https://www.mpi-hd.mpg.de/hfm/CosmicRay/ChLight/Cherenkov.ht.... Also, hello! my name is Ryan & we are likely in the same field.
- AnarchismIsCool 3y agoI spent some time doing testing in a similar facility doing things with gamma irradiation and I'm amazed that they all look like they were constructed by crazy people in their garage. Like really janky mechanisms for moving samples and containing radiation, really ugly facilities, stuff laying around everywhere. They all look like the lab of a mad scientist.
- tracerbulletx 3y agoIt's crazy how the GoPro survived, and the little lcd gauge got fried. Those things are so impressively tough.
- InitialLastName 3y agoA half-inch thick lead box is a lot more help than the gauge gets.
