During the January shutdown, we decided to test the two Q315R detectors that used to live in beamlines 5.0.1 and 5.0.2. Fortunately, they still work! Once Gemini is commissioned (at the end of this year, if all goes well) then we will have to take the Pilatus out of 5.0.1 and move it over to Gemini. Therefore, good to know that the Q315R is still good. Here it is being tested on the floor at 5.0.1.
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.
Once again, the BCSB teamed up with several other groups at the ALS to host a booth at the ACA. It was great to hang out with our ALS colleagues and to see many of our users.
Sadly, today was Charlie Eigenbrot’s last PRT meeting, since he is retiring from Genentech in June. We will miss him! (But we do hope we comes back to visit us periodically at the synchrotron)
We are back up from the long ALS shutdown, and the beamlines are in good shape. We completed a number of projects on the sector 5 beamlines, in particular, as well as performed maintenance on a number of systems: – Pilatus3 6M installed on 5.0.1. The install went well, and…
The next test is to run the 501 and 502 Pilatus detectors simultaneously off the same PPU.
We measured the temperature at the sample during warming of the pin base, and preliminary tests so far show that the heat is not transferred to the loop during two minutes of base warming. Tests are continuing now to determine how well the warmer removes ice and frost from the bases.
