FACET-Facility for Advanced Accelerator Experimental Tests at SLAC-will provide high energy density electron and positron beams with peak currents of roughly 20 kA that are focused down to a 20x20 micron transverse spot size at an energy of 20 GeV. FACET's unique high-power beams will provide important science opportunities in many fields. FACET is one of two facilities that will meet the Department of Energy Mission Need Statement for an Advanced Plasma Acceleration Facility. With FACET, the SLAC linac will support a unique program concentrating on second-generation research in plasma wakefield acceleration with further time allotted for Dielectric Wakefield experiments. We also allow for smaller experiments that can take advantage of the high power FACET beams and are looking to expand our user community to include studies with THz radiation.

The first User Run began in April 2012. We look forward to our second User Run in 2013.

Please join us for the 3rd FACET User Meeting at SLAC this October. On the agenda will be machine performance and plans, experimental results from the first User Run, User wishes for the future and the future goals for FACET.

On the 11th and 12th October, we will hold the 3rd SAREC review of experiments and proposals and Users are welcome to stay for the review.

Please contact one of us with any questions. We look forward to seeing you this summer.
