gaas detector
解釋
砷化鎵探測器-
At present, this kind of gaas photoconductor detector has had practical value. it can detect x - ray, gamma - ray, laser pulse successfully
目前，我們研製的gaas探測器已具有一定的實用價值，可用在室溫下對x射線、射線、激光脈沖進行探測。 -
After measuring dark current, photocurrent and response to x pulse of gaas detector before and after 1. 7 mev electronic radiation, the response tune, fall time of trailing edge, full width of half maximum ( fwhm ), sensitivity, carrier life, mobility are researched and contrasted. the result shows that the response speed of detector, time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation. though sensitivity of the detector reduces, its measuring range can be widened
為了使探測器的性能得到進一步的提高，我們對其進行了電子輻照改性，並測量了本徵砷化鎵探測器和經過1 . 7mev電子輻照的探測器的暗電流、光電流及對x射線的脈沖響應，並對其響應時間，后沿下降時間，半高寬（ fwhm ） ，載流子壽命，靈敏度進行對比，研究，結果顯示經電子輻照后的探測器的性能得到了改善，使響應速度，分辯率進一步提高，並消除了探測器輸出信號后沿的非線性，雖靈敏度有所降低，反而使其測量范圍得以拓寬。 -
