论文摘要
在SLAC上构建了Linac到End Station A（LESA）光束线，并将向SLAC端站A提供近CW的多gev电子光束，以进行粒子物理实验。 LESA的第一半已经准备好在2222财年结束时进行调试，并且完整的光束线将是Q1 FY24。低电流的多GEV电子束是由LCLS-II/LCLS-II-HE-HE-HE-HE-HE-HE-HE X射线游离电子激光器的超导RF（SRF）LINAC寄生产生的。 LESA旨在托管实验，以检测光暗物质，例如轻质暗物质实验（LDMX），以及需要近CW电子电流的广泛的其他实验和测试梁，范围从PA到μA。
The Linac to End Station A (LESA) beamline is being constructed at SLAC and will provide a near-CW beam of multi-GeV electrons to the SLAC End Station A for experiments in particle physics. The 1st half of LESA is ready for commissioning at the end of FY22 and the full beamline will be operational Q1 FY24. The low-current multi-GeV electron beam is produced parasitically by the superconducting RF (SRF) linac for the LCLS-II/LCLS-II-HE X-ray Free Electron Laser. LESA is designed to host experiments to detect light dark matter such as the Light Dark Matter eXperiment (LDMX) as well as a wide range of other experiments and test beams requiring near-CW electron currents ranging from pA to μA.
