LCLSTN0012IntroductionOne of the many technical challenges for future freeelectron lasers FEL and linearcolliders is the measurement and diagnosis of their extremely short electron bunchesThe r. SA Abstract The LCLS project at SLAC requires 40 undulators 33 in the beam line 6 spares and one reference undulator A new facility was constructed at SLAC for tuning and fiducializing the undulators The throughput of the facility must be approximate SA Abstract The LCLS project at SLAC requires 40 undulators 33 in the beam line 6 spares and one reference undulator A new facility was constructed at SLAC for tuning and fiducializing the undulators The throughput of the facility must be approximate How it works….. Electrons are boiled off in the cathode (negative terminal). Electrons are sped up through accelerating plates (parallel plates with a potential difference). Electrons are deflected by a second (and third) set of deflecting plates. LCLS. Linac. Upgrade. LCLS-2. Topics Mentioned. SLAC pieces under discussion. Linac. Coherent Light Source success.
