Hi Garib, Tim and James, Thank you for the helpful information. I look forward to testing this out on some of our data. Hopefully it helps! To Garib, I think that electron diffraction/microED of small molecules is actually in a pretty good position for this technique to really take off. To your c

Dear all, We have an immediate opening for a PhD position at the ESRF in Grenoble (France) in collaboration with the CFEL in Hamburg (Germany) to work on methodological developments in time-resolved protein crystallography at synchrotrons. For further details, please see here: https://esrf.ge

Dear Tim, I understand the problem. If the problem is the distance only then only one parameter is needed for refinement of lattice parameters. I do think that microED has good potential. However engineering problems need to be sorted out (detector, crystal handling, rotation etc). When the

Hi Tom Welcome to the old folks club! There are a few points in your post that I think are incredibly relevant here, and worth picking out for the casual reader - > it takes so little time to calibrate using powder diffraction Exactly! For a user collecting on a modern beamline that can coll

Dear Garib, thank you very much for the details! If everything goes to plan, we are going to use the Dectris QUADRO in September(ish), ideally also with some protein crystals. In ED, distance calibration is more difficult than with X-rays because of instabilities in the lens system (at least with
