Fucked if I know, I've only ever messed around with positrons in cloud chambers, my university wasn't big enough to have one.

I live in 100 000 town, and I think they've got one in hospital, maybe few, is your university really unable to have spare parts from PET scan?

What parts would be useful specifically?

Any sharp object going trough skin, especially something one atom sharp should be considered invasive procedure.

They even think, my brainscan won't differ if I'll be on glucose, not having starch in diet.

Such as? I know certain parts wouldn't be as useful to create a linear beam

Gamma detectors that can see pictures not just values seem to be useful to me. Emmision there is caused by different room in hospital, where they have radioactive compounds. You cannot obtain accelerator by deconstructing pet scan, but you can see positrons in high res.

Yeah I know. But what other machines could you be cannibalizing parts from in order to keep costs down?

Depends on what you mean by a beam. Some positron emitters are commercially available and rely on radionuclides that decay through beta-plus emission. Most positron sources for accelerators rely on particle beams incident on a target. The LEP pre-injector relied on a ~200 MeV electron beam hitting a tungsten target to induce positron production.

I think this was the method I think OP was looking at.

Bro if you ask that question, please don't attempt whatever you're trying to do. You're not qualified. Radiation is not a joke. I've experienced it accidentally, even in low doses shit was painful, I felt like my arm was decaying at every joint.

Sodium-22 decay.

Where do you even get radioactive isotopes, assuming you're not making them yourself.

Go be a sperg elsewhere, unless this is a Cherenkov radiation joke, radioisotopes have all kinds of civilian applications. Hell for some of them you don't even need an NRC license to posses.

I'm assuming that OP is going to have some concrete blocks and/or lead as some form of shielding.

>>16299080
How would OP acquire and setup a 100+ MeV accelerator to produce bremsstrahlung gammas with high enough energy for pair production without it occuring to them at any point in the process that they'd need radiation shielding?

Just buy it online, it's not that hard to find vendors.
