LAT Instrument Integrated with Spacecraft

The LAT instrument (covered for dust protection), has been mechanically attached to the GLAST spacecraft below, which sits on wheels to be moved to different testing stations.

On December 8, a crane lifted the Large Area Telescope (LAT) onto the Gamma-ray Large Area Space Telescope (GLAST) spacecraft, bringing the instrument a few meters and a giant leap closer to space.

In a clean room in Gilbert, Arizona, 15 people from SLAC and the aerospace company that built the spacecraft—General Dynamics Advanced Information Systems—carefully guided the LAT into place and mechanically attached it to the spacecraft. The instrument weighs about 7,000 pounds, while the spacecraft is a diminutive 2,000 pounds. Packed into a Delta 2 rocket, the ensemble will be launched into space later this year.

"The integration of the LAT instrument onto the spacecraft is a major milestone for the GLAST program. The instrument performance has met or exceeded all expectations," said LAT Project Manager Ken Fouts.

The instrument and spacecraft are now undergoing "full functional" tests, to make certain that everything responds correctly. GLAST program personnel from SLAC and the Naval Research Laboratory continue to work owl shifts in Arizona, running tests and checking the data the LAT generates when cosmic muons flow through it.  Read more...

Test Groups Commission New Macromolecular Crystallography Device


The Uni-Puck

The Stanford Synchrotron Radiation Laboratory (SSRL) has a new gadget. The Uni-Puck device, a storage container for macromolecular crystal samples, compatible with the many automated robotic sample mounting systems, had been initiated at SSRL and developed in collaboration with Lawrence Berkeley National Laboratory's Advanced Light Source (ALS), the Advanced Photon Source's Structural Biology Center Collaborative Access Team (APS SBC-CAT), the Cornell High-Energy Synchrotron Source (CHESS), Brookhaven's National Synchrotron Light Source (NSLS), and the Rigaku-Molecular Structure Corporation (Rigaku-MSC).

The puck is currently available for use at several beamlines that use the ALS robot system; at SSRL the Uni-Puck is being commissioned by several test user groups and it is expected to be released to general users in February 2007.

Lab Receives DOE
"Best in Class" Award

Yesterday morning, Acting DOE Site Office Manager Aundra Richards presented Keith Hodgson with a "Best in Class" award for pollution prevention on behalf of the Office of Science. The award recognizes SLAC's dedication to environmentally friendly practices, as demonstrated by the lab's chemical management system (CMS).

Under its CMS, SLAC works with a single service provider, which supplies and manages all of the lab's chemicals. This simplifies the chemical delivery process, increasing efficiency and cutting down on waste. An article describing the CMS program in more detail can be found here.

Congratulations to all involved in the CMS!
