Abstract

A new type of ceramic scintillator has been developed for lost alpha measurement on ITER, where severe environments for measurement, such as high temperature, high neutron/gamma flux and difficult accessibility are anticipated. The characteristics of ceramic sheets in which scintillation materials are blended have been tested using a plasma source and a low-energy helium beam of 7 keV. Scintillation efficiencies are degraded by continuous bombardment of ion beams, and are saturated at doses exceeding 10¹⁷ ions/cm². The scintillation spectrum, the efficiency to electrons and the efficiency to ions are dependent on the materials blended.
