Title:
GAS ELECTRONIC AMPLIFIER AND METHOD FOR MANUFACTURING GAS ELECTRONIC AMPLIFICATION FOIL AND A RADIATION DETECTOR USING GAS ELECTRONIC AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2007/100029
Kind Code:
A1
Abstract:
A gas electronic amplifier employing interaction by photoelectric effect of radiation and gas in which spread of electrons can be reduced as compared with before without lowering the amplification factor of electrons, and positional resolution is enhanced while a high electron amplification factor is provided. The gas electronic amplifier comprises a chamber (102) filled with gas, and a single gas electron amplification foil (12) arranged in the chamber, wherein the gas electron amplification foil is composed of a planar multilayer body having a planar insulation layer (12a) of a high molecular polymer material about 100-300 μm in thickness, and planar metal layers (12b, 12c) covering the opposite sides of the insulation layer, and a through hole structure is provided in the planar multilayer body.
