[3dem] energy filters on FEI TF-20 (cryo)?

[Charles Sindelar]

Hi all,
I am wondering whether anyone here has installed an energy filter  
(i.e. Gatan GIF) on a 200KV FEI F20.

My suspicion is that it should be straightforward, and significantly  
improve performance with tomography (in the zero-loss mode).

It would nice to have confirmation of this, however.  Does anyone have  
direct experience?  Or is it that 300kV instruments are universally  
used in cryo applications with the GIF?

Thanks for your help!
