Abstract
We report the performance of a VUV-sensitive MWPC with a pad cathode c overed by a solid CsI photon converter. Cherenkov photons produced by relativistic C-12 ions in a MgF2 radiator have been detected with 95% single photo electron efficiency. In the HADES design a resulting figu re of merit N-0 > 66 promises proper operation of the RICH as a fast h adron blind trigger device. Tn addition, we have investigated the scin tillation properties of several fluoro-carbon radiator gases in the VU V wavelength region. A significant emission around lambda similar to 1 70 nm is found for CF4.
