[3dem] CMOS detector for F20

[Dokland, Terje]

I am seeking advice for a new CMOS detector for our Tecnai F20 microscope. 

We have a new Glacios coming in near the end of the year. This microscope is equipped with a Falcon 3 detector, which will probably serve most of our purposes. However, our F20 has a Gatan K3, which seems a bit of a waste, and would probably be better utilized on the Glacios. However, that would leave the F20 without a detector, so we’re thinking of acquiring a good quality CMOS detector to put on the F20. 

The F20 will be used for negative stain/room temperature application, training, and some cryo-EM screening purposes, but I imagine most of our data collection and cryo-EM screening will be on the Glacios. Nevertheless, we want a decent detector that is fast enough to do frame alignment and good enough to collect data for 2D classification etc. We are thinking of the Gatan OneView. I would welcome other suggestions with similar capabilties that fall into a similar price range. 

Thanks!
