Another Day, Another Dewar

Simon in a tie! Must be review time for the ALS-U…

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

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 tests with x-rays show that…

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.

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.
