SSCL RFQ‐DTL matching section instrumentation

A description of the SSCL RFQ‐DTL Matching Section instrumentation is presented with emphasis on design issues and early instrumentation commissioning results. The H− beam energy through the RFQ‐DTL matching section is 2.5 Mev, the beam current is 27 mA with a pulse width of 35 μs. The typical beam diameter is 3 mm. The instrumentation consists of three beam position monitors (BPM), a wire scanner, beam loss monitors (BLM), a slit and collector emittance measurement unit (EMU), a current toroid, and a Faraday cup. The instruments were designed to accommodate high current densities, have a large dynamic range with moderate bandwidths, and fit congested spaces.
