对一已研制成的响应精度优于０．１ｍｍ的超短脉冲（ｎｓ／ｐｓ）束流位置监测器中的电子学电路于在线安装前对其监测器的电中心进行了校准，以保证实际测量精度不变劣。对此校准技术作简单介绍并给出相关的校准电路 An electronic circuit in an ultra-short pulse (ns / ps) beam current position monitor, which has been developed to better than 0.1 mm response accuracy, is calibrated to the electrical center of its monitor prior to on-line installation to ensure real Measurement accuracy is not bad. This calibration technique is briefly introduced and the related calibration circuits are given
