[Sem] Retaining the SEM and building a sputter coater

Actually, here's a pair of Mini Convectrons for about $40 shipping included. We really could use 2 or 3. The one pictured has 1/8" npt fittings, which are probably the most practical for us at this point. 

Ebay item # 
231013652852

I'm short on cash, but I could clean, test, and calibrate them. Anyone feeling flush with $40?

Oh BTW how big is that diff pump? Water cooled I bet?

I've been reading about how silver is a practical alternative to gold for sputtering specimens. Looks promising.

FWIW I am converting my vacuum system from diffusion to turbo pumped.  Assuming it works (they are really expensive working so I had to piece it together from eBay after doing a bunch of research) I may have a Varian diffusion pump to donate to NB for SEM / sputter system use.  I will try to play around with coating on my setup in the near future.

Let me know if there is interest for people to discuss and plan
      things out.  I can usually only meet on weekends though.

Well it's a bit of a catch-22. As long as there's ongoing interest in the SEM and we can keep it and the space free from decay, the SEM can stay. If it's underutilized and falls into disrepair, it should go somewhere it might be better appreciated.

        It should be fairly simple to do. I've seen some pretty poor
        designs on YouTube that still sort of work. I think we could
        build a pretty nice one over 2 or 3 months of weekends, tops.
