Abstract

A photon beam-position monitor using a diamond foil as a position-sensitive device has been developed for use on insertion-device beamlines of third-generation synchrotron radiation facilities such as SPring-8, and was tested on the undulator beamline of the Tristan Super Light Facility at KEK. The beam test results show that the diamond monitor can be operated in a photoconductive mode like a semiconductor detector. It has a linear working range of about +/-1 mm and a position sensitivity of less than 3 mum. The stability of the monitor was confirmed by continuous operation under low photon beam intensity conditions.

摘要

已开发出一种使用金刚石箔作为位置敏感装置的光子束位置监测器，用于第三代同步辐射设施（如SPring-8）的插入式装置光束线，并在KEK的Tristan超轻设施的波荡器光束线上进行了测试。束流测试结果表明，金刚石监测器可以像半导体探测器一样在光电导模式下运行。它的线性工作范围约为±1毫米，位置灵敏度小于3微米。通过在低光子束强度条件下的连续运行，确认了监测器的稳定性。
