在核物理实验中,进行能量与速度的关联测量来鉴别重离子的质量和能量已成为一种被广泛应用的技术,建立良好的飞行时间测量系统是开展初始裂变产物测量的关键技术。本研究工作采用微通道板探测器拾取粒子飞行时间信号。此时间探测器由一个碳膜架、一个电子加速栅、一组电子偏转栅和一个带50Ω阳极的微通道板组成。碳膜的质量厚度可根据其尺寸大小(直径16 mm),考虑其机械强度来选取,调试时选为 In nuclear physics experiments, the correlation measurement of energy and velocity to identify the mass and energy of heavy ions has become a widely used technique. Establishing a good time-of-flight measurement system is the key technique to measure the initial fission products. This work uses micro-channel plate detector to pick up the particle time of flight signal. The time detector consists of a carbon mask, an electron acceleration grid, a set of electron deflection grids and a microchannel plate with a 50Ω anode. The quality of the carbon film thickness according to its size (diameter 16 mm), considering its mechanical strength to choose from, when debugging
