A DETECTOR FOR RADIATION, PARTICULARLY HIGH ENERGY ELECTROMAGNETIC RADIATION |
摘要 |
A detector for radiation, particularly high energy electromagnetic radiation is provided. The detector includes a converting section including a cathode for converting the radiation incident on the converting section in electrons by the photoelectric effect. The detector further includes a gas electron multiplier for generating an electron avalanche from electrons which are generated by the converting section and enter the gas electron multiplier, the gas electron multiplier including a first electrode, a dielectric layer and a second electrode, the first electrode being disposed at a first side of the dielectric layer adjacent to the converting section and the second electrode being disposed at a second side of the dielectric layer opposite to the first side. The gas electron multiplier includes a number of holes filled with gas, the holes extending through the first electrode, the dielectric layer and the second electrode. |
