I am making a proof-of-concept linear accelerator with one stage at home ( if i can call it such ).The vacuum chamber is a 40cm transparent pipe with a radius of 10mm.The particles are accelerated by an electrical field created at the two ends of the tube with a voltage of 20kV.I need an electron source so i have thought of using the crt screen filament but the screen contains some toxic chemicals.I think that vacuum tubes also have a similar filament but I don't know if any part of the vacuum tube or if the filament is toxic too.There is also one implausible concern about x-ray radiation.Do i need any kind of shielding for this small model?I also read that the radiation produced with up to 10kV is negligently low - is that true and what do i have to do if i push it past 10kV?Is safety a concern at all (except for the HV power supply) ?
