After our last PRT meeting on Nov 4, Steve Rossi took a group on a tour inside the ALS ring to point out the future site of the Gemini insertion device. This month and next are a great time to visit the ALS, since the ring tunnel is open and available for touring.
As it turns out, Anthony, Marc and Stacey are professionals, with their own shoes and all!
These are the dewars that shipped on Monday May 5, the first day of the ALS shutdown. Thirty of those are from the BCSB beamlines!
Anthony installed the first pin base warmer on 5.0.2 today. We have to wait until the ALS has LN restored before we can test it. One thing to note: the people we spoke to at NE-CAT about their pin base warmer told us that it does not actually solve the icing issue completely. They still do see pins move on the goniometer after mounting. Hopefully the warmer will help a bit, though!
ALS is down for the month of July and the first week or so of August. We are taking the opportunity to do a bunch of preventative maintenance on our beamlines. Some of the items include: – cleaning the Be window on 502 (may help to decrease scatter in images) – replacing air lines –…
Recently, Marc helped a user run some crystals which the user had arranged to have grown in zero-gravity. Here are pictures of the crystal capillaries mounted at the beamline, and the raster grid used to locate crystals within a capillary.
We are very fortunate to have an outstanding Scientific Advisory Board for the new beamline (“Gemini”) we are building in sector 2 at the ALS. The board members are: Bob Fischetti (APS), Dan Harrington (SSRL), Gwyndaf Evans (Diamond Light Source) and Dan Harrington (SSRL). All of the committee members have extensive experience in building microfocus…
