The compact dynamic beamstop (formerly known as the diode beamstop) has been announced as a finalist for this years R&D100 award! Simon Morton and Diane Bryant are invited to the Awards Banquet in Washington DC later this year.
The new Pilatus3 6M detector has arrived and is on the optical bench at 5.0.2, ready for testing tomorrow when we get light!
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!
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!
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.

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 –…
