Just hope he understands how to make good shielding (for himself and others who may be near if this isn't in a proper lab) and has proper radiation (read x-ray) detection equipment.

Proper shielding of the high energy x-rays would be an absolute necessity.
This means not only shielding the direct path between the operator and the device as most people here do, he also needs shield against x-rays scattered back from the walls above and behind the fusor. He should really learn about radiation protection before trying to operate a fusor at these levels.

hi,John
I'll show it to him. Another question,where did you buy your Pressure gauge? I've looked for Pressure gauge which can measure 10^-5pa.

I have observed backscatter from my system if operated at 50 KV (still just doing air, once I get off the computer it will be back to building the gas handling system). I'm probably going to have to give up on the mirror route and use a video camera (found a "cube camera" that I forgot that I had) and totally shield the viewport area to get rid of the backscatter.
The more reactive the materials, the more spectacular the failures.
The testing isn't over until the prototype is destroyed.

just look for cold cathode ionisation gauges on ebay there are plenty there
Edwards
Phillips Granville
Varian
Leybold
Dynavac
10^-5 Pa = around 10^7millibar
all make these
