Another Day, Another Dewar

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!

Dectris was here at the ALS during the recent 2-bunch mode, and re-installed two of the modules on the Pilatus detector on beamline 5.0.2. Users may not have noticed, but the detector was previously missing panels on the far edges. These are now in good working order, and several test data sets have been collected…

The next test is to run the 501 and 502 Pilatus detectors simultaneously off the same PPU.

Our second User Forum was on March 4, in which we discussed the purchase of a pixel-array detector for beamline 5.0.2. The exciting news since then is that we will be able to purchase a Pilatus 6M for the beamline. Expected delivery is in September of this year.

The third User Forum was on April 2, in which we discussed the diode-beamstop device which the BCSB is developing (allows measurement of flux during data collection), as well as the MiniKappa interlocks on beamline 5.0.2, which will now allow a full 360 rotation of omega (sometimes called Phi) with a maximum kappa angle of 55 degrees.

The robot dewars have been taken off of 502 and 503 in order to replace the motors and perform maintenance on the stages.

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.
