Description
SLAC is developing an electron beamline for End Station A, fed from our superconducting Linac LCLS-II-HE. The new beamline enables a continuation of the ESTB program, which ended in 2019, with new high-rate capabilities. A successful test run was conducted end of 2025 before a long shutdown. We expect the new LESA beam line to be operational in Summer 2027, delivering 8 GeV electrons to Users. Beam parameters are varied, from single and multiple electrons to full bunches of up to 100pC at 10th, 100th and kHz rates, potentially even special bunch patterns at nsec bucket distances. We will present the results of the 2025 test run and the expected future capabilities and available experimental infrastructure.
