Abstract
The performance of a new gaseous photodetector was investigated. It consist s of a solid photocathode and a gas amplification structure of the MICROMEG AS type. Using a mixture of helium and isobutane at atmospheric pressure, a stable and high amplification gain close to 10(7) was achieved. Such a hig h gain and small fluctuations allowed the detection of single photoelectron s with a time resolution better than 700 ps. These performances are compara ble with those obtained with the best photomultipliers. (C) 2000 Elsevier S cience B.V. All rights reserved.
