Are you sure your units are right? I have never heard of anyone reaching 1E-10 with a turbo. Best I have seen is E-8. Perhaps someone with more experience can weigh in.

What are the time units? Minutes? Days?

Nice work though!

The x-axis is AMU ... these are all single scans that take about 1 minute

Ah, I see. I apologize, I misunderstood. Thought time was the x-axis . Nice plots.

SRS! Top drawer stuff. I picked up a brand new, in-box SRS 0-3kv digital controlled PMT, Proportional tube power supply. List price $1900 at a hamfest for $250. Best supply I have ever seen. I powers my 5" Bicron NaI:Tl gamma spec tube into my canberra gamma spec. with it.

I have always lusted after an SRS RGA but lacked the $3000 to own a new one. But...who an I kidding... I would have to completely redo my system to hit 10e-6 torr.

Great system Joe ...

I actually wonder what the cheapest RGA out there is. It looks like many are available for a couple thousand...
