Beam diagnostic layout requirements for SSCL linac

摘要

A basic set of diagnostics is needed to commission, tune, and monitor the operation of the SSCL linac. This set of diagnostics has been refined in the final stages of design of the linac. Planned diagnostics include current monitors, Faraday cups, beam loss monitors, beam position monitors, wire scanners, absorber-collector phase scan units, slit and collector emittance measurement units, and longitudinal bunch shape monitors. The diagnostics are described and their placement along the linac is given. The use of the diagnostics for tuning the linac is described. The first set of diagnostics will be installed with the RFQ, with additional diagnostics installed with each linac section.
