【摘要】 本文描述了蒂锌镉探测器(CZT探测器)的一体化设计及其测试。当γ射线、X射线穿过碲锌镉晶体产生电子空穴对,并由晶体表面电极收集形成电荷脉冲。电荷脉冲进入由前放CR-110、成型放大器CR-200组成的一块集成电路板,从而对信号进行成型与放大。CR-110、CR-200集成电路板由+5V供电。文章给出了CR-110、CR-200集成电路板的设计与测试过程。更多还原

【Abstract】 In this paper describes the pedicle zinc cadmium detector(CZT detector) integrated design and test. When γ-rays, X-rays pass through the cadmium zinc telluride crystals generated electron-hole and electronic formed by the crystal surface electrodes to collect the charge pulse. Charge pulses enter the circuit board that is consisted by charge sensitive preamplifier CR-110 and Gaussian shaping amplifier CR-200.The signal is shaped and amplified through the board. The CR-110, CR-200 IC board is supplied by a +5 V input, ± 12 V,-130 V output of the power supply board. Article gives the design and testing process of the CR-110、CR-200 IC board and the power board.更多还原
