[Sneap] He-3

[Paul Barker]

Sneapers,
I need a He-3 beam, and so need some He-3 gas to use in the ion 
source. A quote from Chemgas (around 3500Euro for 20 
atmosphere-litres) was more than I could afford. Does anyone have an 
idea about a cheaper provider ? Can one obtain it "secondhand", i.e. 
essentially lying around, unused ? I have had some success buying NIM 
and Camac electronic modules from a secondary supplier, so maybe it's 
possible
Thanks,
Paul Barker
