Abstract

We schedule to install wire scanners for J-PARC (Japan Proton Accelerator Research Complex) linac in order to measure beam profile and emittance. They have been designed to capture electrons in H- beam, and 7μm-diameter carbon wires and are 30μm-diameter tungsten wires are used for 3MeV and 50-181MeV beam, respectively. In this paper, we report the result of the beam test with 3MeV beam performed at KEK and the calculation about signal and wire temperature. WIRE SCANNER DESIGN J-PARC linac is being constructed [1]. We have developed wire scanners for the measurement of beam profile. We schedule to install 36 wire scanners at linac in total. Four wire scanners are at MEBT1 between RFQ and
