In the frame of the in-kind contribution agreement signed with ESS, CEA is going to deliver to the European Spallation Source five Non-invasive Profile Monitors (NPMs) to be installed in the Cold Linac section. The high density of the proton bunches, typically 10 9 proton in a few mm 3 , may lead to space-charge effect distorting the profile measurements. Studies to contain the space charge effects have been performed. Two different read-outs (current reading from metallic strips and optical) were proposed and tested in two measurement campaigns at the IPHI accelerator at CEA Saclay. After careful analysis, the final choice fell on the read-out composed by a micro channel plate equipped with a phosphorous screen and followed by a camera. The detectors are now in construction at CEA. A summary of all main steps of the project, with special focus on the space charge simulations and the experimental campaigns, will be presented.

五个用于ESS Cold Linac的横向光束轮廓仪

在与ESS签署的实物捐助协议的框架内，CEA将向欧洲散裂源交付将在冷直线加速器部分安装的五台非侵入式轮廓监测器（NPM）。质子束的高密度（通常为几mm 3中的10 9个质子）可能导致空间电荷效应，使轮廓测量值失真。已经进行了包含空间电荷效应的研究。在CEA Saclay的IPHI加速器上，提出了两种不同的读数（从金属条和光学件上读取电流）并在两次测量中进行了测试。经过仔细分析，最终的选择落在了由装有磷光屏的微通道板和照相机组成的读数上。现在，CEA正在建造探测器。该项目所有主要步骤的摘要，
