Physics requirements of commissioning diagnostics for SSCL linac

Commissioning diagnostics are described in terms of the beam physics requirements of the SSCL linac. Commissioning diagnostics include current monitors, beam position monitors, spectrometer, foil scattering experiment, wire scanners, Faraday cups, and bunch shape monitors. Two DOE integrated contractors, the Superconducting Super Collider Laboratory and Allied Signal, Kansas City Plant, are developing the commissioning diagnostics. The need to measure bright, short linac beam pulses requires special design considerations. High density harps and collectors with up to 50 wires per cm and 128 wires total, and fast, 3.5-MHz amplifiers have been developed. The diagnostics will be first used and tested during beam commissioning of the RFQ
