| Abstract | Thick carbon foils (>300 μg/cm2) has been used for stripping of H ion beam at the 3GeV Rapid Cycling Synchrotron (3GeV-RCS) of J-PARC, where foils with long lifetime against high temperature >1800oK are strongly required for efficient accelerator operations. The key parameter to the foil lifetime is foil temperature attained during irradiation. We have recently developed a new irradiation system for lifetime measurement using the KEK 650keV Cockcroft-Walton accelerator with high current pulsed and dc H beam, which can simulate the high energy-depositions upon foils in the RCS. During irradiation tests by this system, the temperature of foil is measured by a thermometer in a dc mode, and by using a phototransistor in a pulsed mode. This paper describes the pulsed measurements with 3mA-peak current, 0.25msec duration and 25Hz repetition. |
