论文摘要
Paul Scherrer Institut（PSI）的高强度质子加速器（HIPA）回旋子提供590 MEV CW质子束，最大功率为1.42 MW。提取后，将梁在120 m长的通道中转移到两个目标站（TGM和TGE）以进行表面启动的产生，然后再将其剩余功率沉积在散布目标SINQ上以进行中子产生。作为高强度隆隆声光束线（HIMB）可行性研究的一部分，这些目标中的第一个将被较厚的目标替换为较厚的目标，从而增加了表面隆隆声的产生速率。但是，HIMB的主要挑战是将质子束损失保持在最低水平，这需要提高我们对MW级梁线分布式损失的理解。为此，开发了一种新的方法，其目的是将温度，光束曲线测量值以及光束电流测量值与使用Monte Carlo Simulation工具的组合功率沉积计算和主要光束损耗相关联。
The High Intensity Proton Accelerator (HIPA) cyclotron at the Paul Scherrer Institut (PSI) delivers 590 MeV CW proton beam with a maximum power of 1.42 MW. After extraction, the beam is transferred in a 120 m long channel towards two target stations (TgM and TgE) for surface muon production before depositing its remaining power at the spallation target SINQ for neutron production. As part of the High Intensity Muon Beamline (HIMB) feasibility study, the first of these targets will be replaced with a thicker one thereby increasing the rate of surface muon production. However, a key challenge for HIMB is to maintain the proton beam losses to the lowest possible levels which requires improving our understanding of the distributed losses along the MW-class beamline. To this end, a new approach was developed where the aim is to relate the experimental values of the temperature, beam profile measurements as well as beam current measurements to the combined power deposition calculations and primary beam losses using Monte Carlo simulation tools.
