SLAC commitmentSLAC commitment

Statement from the SLAC Director

“The LCLS and its expansion are critical ingredients in the broad scientific portfolio of the SLAC site for the coming decades. I encourage the LCLS team to consider the unique possibilities that the full capabilities and flexibility of the SLAC linac, including electron beams up to 50 GeV, will offer. Further, I encourage them to integrate these possibilities into the plans for the expansion of LCLS beyond its baseline operating parameters.”

“SLAC and its talented staff of accelerator physicists and engineers routinely operate the linac in a multi-user mode with high operational efficiency. For example, the linac currently serves to inject the B-factory in parallel with fixed target high energy physics experiments and accelerator R&D. We expect that such operational flexibility will enable the linac, with suitable modifications, to serve the needs of an expanded LCLS well into the future.”
