Saclay CEA/IRFU正在与欧洲散裂源签署实物捐助协议的框架内，致力于提供五台非侵入性剖面监测仪。2 GeV质子束撞击钨靶产生的散裂反应将产生中子。为了加速质子，一个5MW的强力直线加速器正在建设中。诊断装置是对机器进行调整和保护的必备工具。非侵入式剖面监测仪提供了波束传播横向方向上的波束剖面测量。该项目提出了几个物理和技术挑战，包括离子或电子的低信号检测，由束流空间电荷效应引起的轮廓扭曲和电场的不均匀性。为了证明探测器的性能和可行性，对探测器的关键部分进行了仿真和建模。已经制造了一系列具有不同读数类型的原型，并在3MeV质子加速器IPHI的实际条件下进行了测试。在实际梁条件下的试验表明，它们都有各自的优点和缺点。本文给出了各种配置读出系统的测试结果，与探测器的模型和仿真相吻合。在结束语中，我们将讨论原型的性能，并指出基于摄像头的原型更适合最终设计。
Saclay CEA/IRFU is working for the delivery of five Non-Invasive Profile Monitors in the frame of the in-kind contribution agreement signed with the European Spallation Source. Neutrons will be produced by spallation reactions of 2 GeV proton beam impinging on a Tungsten target. To accelerate protons a powerful linear accelerator of 5MW is under construction. Diagnostic devices are mandatory tools for the tuning and protection of the machine. The non-invasive profile monitors provide a measurement of the beam profile in transverse directions to the beam propagation. This project raises several physical and technical challenges including low signal detection of ions or electrons, profile distortions induced by the beam Space Charge effect and non-uniformities of electric field. Simulation and model of the critical aspects of the detector have been performed in order to prove the performance and the feasibility of the detector. A series of prototypes has been built with different readout types, and tested in real conditions at the 3MeV proton accelerator IPHI. All of them show some advantages and drawbacks revealed by the tests in real beam conditions. In this paper we present the results of the tests for the various configuration readout systems to agree with the model and simulation of the detector. In concluding remarks, we will discuss the performance of the prototypes and point out the camerabased one to be the more suitable for the final design.
