摘要

一种非侵入式、紧凑的激光线系统被开发出来用于测量H光束的横向发射度，并在欧洲核子研究中心LHC的新型LINAC4注入器上进行了演示。来自低功率脉冲激光源的光通过光纤传输与H光束碰撞，其中一部分被中和，然后由下游的钻石探测器拦截。通过扫描聚焦后的激光并测量光中和粒子的分布，可以重建横向发射度。在LINAC4调试期间，用激光线测量了3 MeV光束的垂直相空间分布，并用传统的狭缝和网格方法进行了验证。

Demonstration of a laserwire emittance scanner for hydrogen ion beams at CERN

A non-invasive, compact laserwire system has been developed to measure the transverse emittance of an H- beam and has been demonstrated at the new LINAC4 injector for the LHC at CERN. Light from a low power, pulsed laser source is conveyed via fibre to collide with the H- beam, a fraction of which is neutralized and then intercepted by a downstream diamond detector. Scanning the focused laser across the H- beam and measuring the distribution of the photo-neutralized particles enables the transverse emittance to be reconstructed. The vertical phase-space distribution of a 3 MeV beam during LINAC4 commissioning has been measured by the laserwire and verified with a conventional slit and grid method.

期刊介绍： Physical Review Special Topics - Accelerators and Beams (PRST-AB), is a peer reviewed, purely electronic journal, distributed without charge to readers and funded by contributions from national laboratories. It covers the full range of accelerator science and technology: subsystem and component technologies, beam dynamics; accelerator applications; and design, operation, and improvement of accelerators used in science and industry. This includes accelerators for high-energy and nuclear physics, synchrotron radiation production, spallation neutron sources, medical therapy, and intense beam applications.
