Abstract
A prototype GSPC without the gas purification system was developed in China Institute for Radiation Protection(CIRP). Xenon filled GSPC has many advantages, including high energy resolution, large detection area, ability for implementing position sensitive detection, etc. It may find a wide application in low energy X-ray and γ-ray fields, e.g., astronomy X-ray detection, medical imaging. Further applications in neutron and charged heavy particle detection are also possible. Several tests for 241Am and 55Fe have been carried out to check out its preliminary performance. Currently the energy resolution is still far from expectation, nevertheless, the concept is proved to be promising and the experimental results suggest the way for further improvements. The possible ways for improvement of the detector performance are discussed in conclusion. This work was funded by National Natural Science Foundation of China.Authorization number:10375054(National Natural Science Foundation of China).
