Behind Every Great LCLS User, Outstanding Beam Operations

University of Western Michigan physicist Nora Berrah wrapped up her research group's five-day run on the Linac Coherent Light Source on October 20. Their project marked the first time that the powerful X-ray laser had been used to study molecules. It was a complex experiment, and Berrah readily acknowledged that the work wouldn't have been possible without the teamwork and cooperation of the LCLS Atomic, Molecular and Optical instrument scientists and engineers.

But she also gave a big nod to another SLAC group that had a more behind-the-scenes role. These were the accelerator operators—the people overseeing the electron beam that drives the LCLS X-ray laser.

"The accelerator operators were absolutely a crucial part of the research team," Berrah said. "We couldn't have done our work without their flexibility in giving us the beam parameters that we requested as well as their interest in our research projects."

The operators craft the LCLS X-ray beam, continually adjusting countless variables to make sure the it meets the specifications of scientists on the other end. But while this role has generally remained the same from one scientific program to the next, the startup of the LCLS has prompted something of a departure in how the operators do business.  Read more...

Live from the Main Control Center: The LCLS Real Time Display

Software engineers with the Experimental Physics and Industrial Control Systems Group in the SLAC Controls Department unveiled the Linac Coherent Light Source Real Time 24 Hour Display last week, giving all SLAC employees and on-site users access to real-time status updates on the LCLS X-ray beam.

The display, which is available to anyone accessing the Web from a SLAC computer, was designed to provide lab administrators with summary information on the status of the LCLS beam. According to EPICS Group Leader Ernest Williams, the display gives lab administrators an at-a-glance summary of facility performance.

"Management wants to know 'how's the machine running today?'" Williams said. "Engineers can use this kind of thing too, but the target audience is the management."  Read more...

A New Location for SLAC Salvage

The Salvage Group has moved to new location. Salvage is no longer located in Building 28. Their new location is the lower level at Interaction Region 8, also called IR 8. Please take all drop-off items to the new location or make arrangements with the Labor Pool to have the items delivered. A salvage form must be filled out just prior to transferring any item to salvage. The Radiation Protection Field Operations Group may need to survey some of the material or equipment before the item is sent to Salvage. See the form (link above) for details.

As a reminder, Salvage should be the first source for re-use prior to making a new purchase. Items received at Salvage change frequently. Stop by and see the new location and see what's available.

For questions or further information contact Gus Venancio (x2329).
