    I'm sure there are multiple physical safety and protocol measures in place to prevent any such occurrence, but what if there were a human inside the LHC tunnel when it was started? Or perhaps more gruesomely, a person were inside an experiment bay when a fully ramped up beam was directed in there? Would their head explode?

    This sounds like something right "up my alley"! Except, thus far, I can only guess that: LHC is referring to some particle path within an accelerator? More, please! jocular

    Ah, I see. Pinholed and irradiated with the greater than full power of a freight train. I wonder what the rest mass of the particles in the LHC beam are?

    Oh, sorry Joc. Large Hadron Collider; Large Hadron Collider - Wikipedia, the free encyclopedia
    I was curious as to just what might happen if the most powerful charged particle beam in the history of human endeavor were to intersect a bit of flesh.

    Look up Anatoli Bugorski and then wish you hadn't looked up Anatoli Bugorski.

    The LHC tunnel is essentially a vacuum when it is started. Otherwise the protons would collide into the air molecules and ruin the experiment.

    the beam pipe is a vacuum. the tunnel that the pipe and magnets are in isn't. i think the op was meaning the tunnel not the pipe.

    Sometimes it is better not knowing than having an answer that may be wrong.

    Hmm.... And the U-70 operates at about 1% the power of the LHC. Sort of a modern version of Phineas Gage.

    The largest energy produced by the LHC in an actual collision is roughly equivalent to the energy contained in a mosquito. I am not making this up, the people at the LHC actually said that.

    Of course the energy in a mosquito to come out of a collision can be regarded as "huge".

    Thank you profusely for this! One of my all-time imponderables involves pondering the effect of high-energy particles impinging upon a person's being. joc

    Appreciate it! At least my guess was only 2/3 wrong! joc

    Your link provides amazing information for one such as myself. I have had a respectful fear of radiation since childhood, for things occult have always frightened me. Few of you will be old enough to remember the device shown below:





    These were viewing fluoroscopes, X-Ray machines, made for, and used by, shoe stores all over the U.S. UK residents: were they there used also? The patron, usually a child, stepped up onto a small platform, inserted both feet wearing the new shoes into an opening, the salesman, obviously knowing nothing of the dangers involved, controlled the exposure time while looking into a view shield along with the kid, and perhaps a parent. The X-Ray tube was a "Coolidge Tube", so marked on it's outside, having two long "ears" in the center of which was a spherical portion about 4 inches in diameter. Two electrodes protruded from one ear, a heavy copper rod about 1/2 inch in diameter from the other. A heat-dissipating finned radiator fit over the copper rod, which ended inside the center of the sphere with a 45-degree angled "target". Could have saved all this "babble", had I searched first, but anyway, here's how it looked:






    The salesman used little discretion, allowing plenty of time for "toe wiggling", observing shoe construction, etc. Sometimes we gaped in wonder for twenty seconds, or more! While doing so, the tube, located below the step-up, beamed it's radiation upwards, through the feet, and on up through the view shields, as well as the sides of the wooden cabinet. Obviously, one pair of shoes looked through involved X-Ray exposure equivalent to several hundred medical diagnostic "shots". I'll give the maker this much (which is very little!), the tube itself was contained in a rectangular lead box of 1/8 inch thick material, probably more aimed at safety from electrical shock, than radiation hazard. The machines had one instrument, a milliameter, instructions indicating 5 ma or more was needed for effectiveness of operation, anode voltage being on the order of 90,000 volts.

    How am I versed in such an obscure rarity? The local store, when ALL such machines were being scrapped, around 1953 or '4, thereabouts, gladly gave the damn thing to this fool writing here, then about 14 years old! If interest is expressed, I'll tell about how I disassembled it, and used it. jocular
