RF & Analog Systems Department
The RF & Analog Systems department develops high frequency electronics for a variety of applications. Large projects include: A nanometer resolution cavity beam position monitor system used for LCLS, LCLS2 and the Pohang FEL systems. Femtosecond beam arrival time monitors for LCLS. Master source and stabilized timing distribution for LCLS and LCLS2. Femtosecond laser-to-RF synchronization for LCLS, LCLS2 and the ASTA Ultrafast electron diffraction system. Broadband readout for microwave multiplexed cryogenic detectors for LCLS2 and Simons Observatory. Smaller projects have included electronics for coherent combining of multiple lasers, microwave “clockwork” for SSRL spin wave experiments and development work on radio telescope front ends.
Key Competencies
