在兰州重离子研究中心冷却储存环上研制了一种由微通道板、荧光粉屏和光信号采集组成的无创电离剖面监测仪（IPM）。它使横束冷却和轨道振荡的实时轮廓测量成为可能和有效的。本文首先介绍了IPM的设计准则，包括理论信号良率的计算、空间电荷场和初始动量的计算以及静电场畸变的模拟。为了研究IPM的性能，在不同的高压设置下进行了光束轮廓测量。随后，还介绍了一些有价值的电子束实验，用于横向电子冷却和轨道振荡的研究。最后讨论了同步加速器发射度爆破研究中快速逐匝剖面测量方法。与HIRFL-CSR注入器上新部署的发射度仪器合作，IPM在注入失配研究中显示出巨大的前景，并且在音调、色散和色度测量中也具有潜在的价值。
A noninvasive Ionization profile monitor (IPM) consisting of micro-channel plates, a phosphor screen and the optical-signal acquisition has been developed at the cooling storage ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR). It makes the real-time profile measurements for the transverse beam cooling and orbit oscillation possible and efficient. This paper firstly describes all the IPM design criterions including the theoretical signal yield calculation, the space charge field and initial momentum evaluation, and the electrostatic field distortion simulation as well. In order to investigate the IPM performance, the beam profile measurements are done with different high voltage settings. Subsequently, some valuable beam experiments about the transverse electron cooling and orbit oscillation study are also presented. In the end, fast turn-by-turn profile measurements for the emittance blow-up research in a synchrotron are discussed. In cooperation with the newly deployed emittance instruments at the HIRFL-CSR injector, the IPM shows great prospects for the injection mismatch study, and potential values for the tune, dispersion and chromaticity measurements as well.
