Space Crystals

A special welcome to our SULI student, Sayan Roychowhury, who is majoring in Electrical Engineering and Computer Science at the University of Illinois. He is here with us for the fall term, and writing code to process visual images of protein crystals and center them automatically in the x-ray beam. SULI is the Science Undergraduate Laboratory Internship program in which the host lab (in this case, LBNL) pays for a student to work for a few months to gain experience at a national lab and to encourage students to remain in STEM fields.

Several BCSB staff teamed up with other ALS beamline scientists to represent the ALS at this year’s American Crystallographic Association meeting in Denver. In the picture are from left to right: Christine Beavers, Simon Morton, Diane Bryant, Stacey Ortega, Jay Nix, Corie Ralston:

The Advanced Light Source is planning a major upgrade, which will result in brighter, more coherent beams. The upgrade will occur in 4-5 years, and so now is the time for the biosciences community to define our vision of synchrotron capabilites for biosciences (scattering, diffraction, tomography and IR methods) in the years to come, and…

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.

We are very fortunate to have an outstanding Scientific Advisory Board for the new beamline (“Gemini”) we are building in sector 2 at the ALS. The board members are: Bob Fischetti (APS), Dan Harrington (SSRL), Gwyndaf Evans (Diamond Light Source) and Dan Harrington (SSRL). All of the committee members have extensive experience in building microfocus…

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!
