COVID-19 Research

NECAT is giving priority to COVID-19 research while accepting all GUP beamtime requests.

New Scheduling Email

Starting this run, we are sending scheduling emails from a central address: necat@anl.gov  Please feel free to send emails to that address if you need to request time as well.   We are letting everyone know of this change, because it seems to be going to SPAM for some people, or getting overlooked since it’s not expected.  

If you have any needs for this run, please feel free to reach out to necat@anl.gov

Dewar Recovery

Sometimes, a dewar arrives warm and without any visible or noticeable breaks in any of the common breakpoints, such as the neck.  In these situations, it is possible that the vacuum has been lost on the dewar over time, preventing it from holding temperature.  NE-CAT can check the integrity of the vacuum by pumping down the dewar, then, while the dewar is under vacuum, Ed Lynch flows helium gas over the outside of the vacuum vessel, especially at the seams.

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.
