Looking for HIGH vac bell jar - Richard has said that he uses models from Fisher Scientific Nagalene - not glass... I didn't see anything in their catalogue that seemed to fit the bill for a high vacuum application... Rich seems to think glass too dangerous... Looking for 12" to 13" diameter range... Looked at "Laskey" (? or something like that web-page.. They have glass bell-jars, but don't specify their vacuum range... ) Would like to have a view port - but want to minimize hazards... More view the better... Any recommendations? Long range target is to go into the 15KV+ range (with appropriate shielding), but would like to view lower voltage ranges safely - is there any "middle ground?" Seraphim - I see you use a glass bell jar - any feedback??? I could put a "bullet proof" lexan sheild around the vacuum chamber - with numerous holes to allow decompression... Would this be acceptable? Want to film activity with Sony TRV900 digital vidio camera. Of course, would provide adequate parafin / lead shielding at higher voltage levels...
Still in initial design phase...
