摘要：

Performance and characteristics of a band-pass photon detector using acetone gas and CaF2 window (acetone/CaF2) have been studied and compared with an ethanol/MgF2 detector. The optimal operating conditions are found to be 4 mbar acetone pressure and 745 +/- 20 V anode voltage. The count rate obtained by us is about a factor of 3 higher than what has been reported earlier for the acetone detector. Unlike other gas filled detectors, this detector works in the proportional region with very small dead time (4 mu s). A detector bandpass of 0.48 +/- 0.01 eV full width at half maximum is obtained.
