A novel gas-filled detector for synchrotron radiation applications
We describe in this paper the performance under synchrotron radiation of a sealed gaseous detector, Vantec-1, operating at high pressure and less prone to discharges. It is consequently operating at high gain (>105) at high local counting rates up to 106 cps/mm2. To achieve these characteristics, a thin resistive layer is used on a glass plate between the mesh and the readout anode. The performanc
