EIGER2 X Detector Repairs

At the start up of operations for the 2021-2 run, it was discovered that one of the cards which aggregates data from multiple modules in the EIGER2 detector on 24-ID-C was faulty.  As a result, NE-CAT was forced to reschedule all users on 24-ID-C for the first week of user operations.  However, Dectris was able to immediately send us a replacement part which was successfully installed by Ed Lynch, Jim Withrow, and Malcolm Capel.  Replacing the card did require removal of the EIGER2 from the 24-ID-C A-frame and its subsequent re-installation.

A Cryptic Site of Vulnerability on the Receptor Binding Domain of the SARS-CoV-2 Spike Glycoprotein

SARS-CoV-2 is a zoonotic virus that has caused a pandemic of severe respiratory disease—COVID-19— within several months of its initial identification. Comparable to the first SARS-CoV, this novel coronavirus’s surface Spike (S) glycoprotein mediates cell entry via the human ACE-2 receptor, and, thus, is the principal target for the development of vaccines and immunotherapeutics.
