The Linac Coherent Light Source (LCLS) is a SASE x-ray Free-Electron Laser (FEL) project under construction at SLAC. The machine commissioning includes the injector, the first and second bunch compressor stages, the linac up to 14 GeV, and the various beam diagnostics. To ensure the vitality of FEL lasing, it is critical to generate and preserve the high quality of the electron beam during acceleration and compression. The final beam quality can be very sensitive to system jitter. To minimize jitter, various transverse and longitudinal feedback systems are required. Here, we report the commissioning experience with these systems during the two phases of commissioning in 2007 - 2008.
