此外，为了同时测量对撞点处正、负电子束的位置，两套带有8电极的特殊束流位置探测器(BPM)将安装在对撞点两侧。
Moreover, in order to measure the positions of both positron and electron in the IP at the same time, two special BPMs with 8-bu.
在与各种探测器比较的基础上，我们设计了微通道板探测器，它是目前用于电子束曝光机的最先进的探测器。
On basis of comparison with other types of detectors, we designed microchannel plate detector which is the most advanced detector for EBM up to now.
电子束半导体探测器的测量精度易受到射线的能量、 剂量率、入射方向和环境温度等条件的影响。
The measurement accuracy of electron beam by using semiconductor detector is easily affected by beam energy, dose rate, beam incidence direction, environment temperature etc.
