Winner: Matt Clifton of Nurix!

It turns out there is a small cyclotron at LBNL! It is used to produce medical isotopes used for PET scans. Some of the BCSB staff were lucky enough to be invited on a tour of the cyclotron, which is in building 56, not too far away from our more familiar synchrotron in building 6.

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 –…

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.

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.
