Abstract
The valuable properties of CVD diamond films used as micro-strip gas chamber (MSGC) substrate are presented and a gas detector with an area of 20x20mm2 was fabricated on a CVD diamond film whose resistivity ranges between 1010 and 1011Ω-cm. We systematically report the energy spectra generated by a 5.9keV55Fe X-ray source. The effects of high potential on the energy resolution are investigated and discussed in detail. A better energy resolution about 12.2% is obtained when MSGC filling with an argon+10%CH4 gas mixture operated at a drift potential of -1100V and a cathode voltage of -650V.
