Title: Characterisation of the Response of Chromium-Doped Alumina Screens in the Vacuum Ultraviolet Using Synchrotron Radiation
Published: December 01, 2002
Abstract: We have measured the response of chromium-doped alumina screens to vacuum ultraviolet radiation and derived quantum efficiency curves for the energy range from 30 to 300 eV. A model is presented to explain the structure in this curve. In addition, the radiation hardness of such screens, which have application as a narrow-band radiation detectors for a hot fusion plasma diagnostic, is reported here for MeV electrons. Finally, a simple model constructed to obtain the carrier diffusion length and the bulk efficiency of this material.
