Abstract
The Linac Coherent Light Source (LCLS) as the world’s first hard x-ray free electron laser in the range of 250 eV to 10 keV at its fundamental wavelength has been operated as a user facility since 2009 with six experimental stations and an increasing range of x-ray beam parameters now available to users. Various aspects of operating the LCLS accelerator to deliver the necessary electron beam in terms of bunch charge, energy, and length for the wide parameter range and different FEL operating modes will be discussed. An emphasis will be on the electron beam diagnostics that are most critical for generating the desired x-ray beam properties. Measurements of electron beam energy, energy loss, and transverse orbit will be shown as well as bunch duration and shape measurements.
