Big Dewar Day – 22 outgoing dewars


Marc collected a lysozyme dataset with the new Pilatus 6M detector. All modules are good.
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.

The BCSB is planning on starting a monthly User Forum to solicit feedback from users on the current and future use of the beamlines. We’d love to hear from you about the direction that the BCSB should be taking in terms of beamline upgrades, features, and general operations. If you are interested in participating in the forum, please contact Corie Ralston.
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.
