It possess many of the physical properties such as high atomic number ( z ) , large enough band gap , high resistivity , relatively low leakage currents , and high intrinsic mobility - lifetime ( ut ) product , which are required for room - temperature nuclear radiation detectors . so it is widely used in nuclear medical imaging system , space engineering , and astrophysics , environmental monitoring , and so on . in addition , it is the best substrate for lattice matched epitaxial growth of hg1 - xcdxte ( mct ) thin films and solar cells 用單晶czt制成的探測器可在室溫下工作,工作溫度范圍寬( - 20 40 ) ,能量探測范圍寬( 10kev 6mev ) ,對x射線、射線能量分辨率高,在x射線、射線成像、天體物理研究、工業探測、安全檢測、核輻射探測、核廢料監控、 x射線熒光分析( xrf ) 、 x射線斷層掃描和核醫學等方面有重要用途。

The use of the state - of - the - art laser facility makes it possible to create conditions of the same or similar to those in the astrophysical processes . the introduction of the astrophysics - relevant ideas in laser - plasma experiments is propitio us to the understanding of the astrophysical phenomena . however , the great difference between the laser - produced plasmas and the astrophysical processes makes it awkward to model the latter by laser - plasma experiments . this paper addresses the physical backgrounds for modeling the astrophysical plasmas by laser plasmas , connecting these two kinds of plasmas by scaling laws . thus , allowing the creation of experimental test beds where observations and models can be quantitatively compared with laser - plasma data . special attentions are paid on the possibilities of using home - made laser facilities to model astrophysical phenomena 采用當前最先進的激光裝置與物質相互作用,可以獲得與天體物理過程中相同或相似的條件,并進而開展利用激光等離子體模擬天體物理現象的實驗.然而,激光等離子體為微米空間尺度、納秒存活時間,而天體物理對象則為宇宙學的極大的時間與空間尺度,對在物理上和實際操作上將這兩種表面上存在巨大差異的物理過程對應起來從而利用激光等離子體研究天體物理過程的可能性進行了討論,特別是對利用國內的激光裝置開展模擬實驗的可行性進行了討論
