Controlling coupler-kick emittance growth in the cornell erl main linac

One of the main concerns in the design of a high brightness Energy Recovery Linac X-ray source is the preservation of beam emittance. Discussed is one possible source of emittance dilution due to transverse electromagnetic fields in the accelerating cavities of the linac caused by the power coupler geometry. This has already been found to be a significant… CONTINUE READING
