H 源和低能束传输 (LEBT) 线将在很大程度上决定 Linac-4 的性能，这是 CERN 预计作为 PS 助推器注入器的新机器。为此，正在建立一个测试台，其中包括电源、LEBT、RFQ 和斩波器线路。到目前为止，仅安装了源代码和 LEBT。首次测量是使用法拉第杯测量总源强度、使用狭缝和栅格发射度计进行横向发射度测量以及使用光谱仪进行能量扩散测量。测量了光束强度、轮廓、横向发射率和能量扩散。本文讨论了在 35 kV 提取电压下对 H 束以及在 45 keV 下质子束进行的测量。 2011 年 5 月 16 日至 18 日在德国汉堡举行的 DIPAC2011 会议上发表的论文 CERN LINAC4* 3MEV 测试台上的光束测量的第一批结果 B.

The H source and the low energy beam transport (LEBT) line will determine to a large extend the performance of Linac-4, the new machine foreseen at CERN as injector into the PS Booster. For this reason a test stand is being set up, consisting of the source, the LEBT, the RFQ and the chopper line. Up to now only the source and LEBT are installed. First measurements have been performed using a Faraday Cup to measure the total source intensity, a slit and grid emittance meter for transverse emittance measurements as well as a spectrometer for energy spread measurements. Beam intensity, profile, transverse emittance and energy spread have been measured. The paper discusses measurements done on H beams at 35 kV extraction voltage as well as proton beams at 45 keV.
