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.
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.
Images of a crystal in a loop before and after using the pin base warmer:
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!
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…
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.
