Chorrax posted:my cousin won't shut up about this so the thing i read about this was basically they predict mini black holes will form in a certain situation if we really do live in a 3 dimensional universe. if they find mini black holes forming with significantly less energy required than that, then it might be evidence for "parallel dimensions" ie the universe might have more than 3 dimensions. it's basically a test for evidence for or against string theory being a thing, not like the comic book multiverses described in that title

Mini black holes are a really long shot- there's no evidence of them being created in eg: cosmic rays collisions in the upper atmosphere at energies way higher than the LHC. The whole parallel dimensions thing is bunk from an experimental perspective because even if there were more than 3D there's p. much nothing that lets us test that hypothesis.

The LHC beam would leave a nice hole in your skull surrounded by extremely radioactive bits of you, assuming you didnt just end up plasma.

i wish super-science was cooler. like you guys aim the beam at the moon and it grows like twice as large, or you aim it at a spider and it becomes a super smart spider and takes over the entire LHC until a team of special ops forces from America has to rescue you all from cocoons and when the gruff-voiced main guy unwraps the hot supermodel scientist you guys he says "now that's what i call a sticky situation" and roll credits.

Actually since Trig is here now maybe we can ask him for recommendations of what kind of fish to put in the collider.

The beam is in really hard vacuum. It's hard to sneak a fish in there without anyone noticing. Cheap dutch beer however...

how wide is the beam anyway? like what's its diameter, and how much of that is focused well enough to use (probably most of it right)

wesley snypes posted:how wide is the beam anyway? like what's its diameter, and how much of that is focused well enough to use (probably most of it right) At the place where the beams collide it's about the width of a human hair. While it's going round the ring it's a bit thicker as it gets focussed then defocussed on either side of the experiments. It's mostly useable but it really depends on how stable it is. You get all kinds of harmonics and chaotic motion and stuff which means bits get shaved off against big gently caress-off collimators as it circulates. I can't give exact numbers as it's several years since we saw collisions, but generally a fill lasts ~7hrs and we maybe 'use up' the beam in half a day assuming it's stable long enough to do so. This is with about 40 million collisions per second in each experiment, and 10^15 protons per beam more or less, so about 0.2% of the injected protons see some action in the experiments on a good fill, and maybe 1/2 - 1/4 get chomped by the collimators. The rest end up splattered over the beam dump.

what is the vacuum in the lhc beam path? when i used ion implanters at my old job we used cryopumps and the vacuum was 1e-6 torr or so but that was also with the outgassing caused by the beam striking photoresist and poo poo on the wafer, i imagine a beamline without an outgassing target gets a pretty rad vacuum. what kinda pumps?

would you want that beam to shoot out of your dilz on command, if you had the choice

not if it only shot once every 4 years and then broke every time

if you just smash it into the beam dump what kinda current is it? do you measure beam current for dosimetry or do you use something else?
