Photon detector performance and radiator scintillation in the HADES RICH

Description

For the HADES collaboration We report the performance of a VUV-sensitive MWPC with a pad cathode covered by a solid CsI photon converter. Cherenkov photons produced by relativistic 12C ions in a MgF2 radiator have been detected with 95% single photo electron efficiency. In the HADES design a resulting figure of merit N0>66 promises proper operation of the RICH as a fast hadron blind trigger device. In addition, we have investigated the scintillation properties of several fluoro-carbon radiator gases in the VUV wavelength region. A significant emission around λ similar 170nm is found for CF4.
