在 CERN 的 SPL（超导质子直线加速器）研究框架内，用于 CERN PS 助推器的新型 160 MeV 质子注入器目前正在开发中。该直线加速器 (Linac4) 不仅是迈向未来多兆瓦超导直线加速器的第一步，而且还可以在中期改善 CERN 质子用户的束流可用性和束流质量。在 Linac4 研究的框架内，并在欧盟资助的联合研究活动 HIPPI（高强度脉冲质子注入器）的支持下，CERN 正在建设一个 3 MeV 测试台。该测试台将探索直线加速器的一些最关键的问题，例如低能量下的光束动力学，特别强调斩波线，该斩波线的设计目的是生成光束所需的时间结构，清理光束光晕，并将其与后续的射频结构相匹配。在此背景下，新的光束形状和光晕监视器正在建设中。光束加速将由 CEA 和 CNRS 之间的 IPHI 合作在法国开发的 RFQ 来执行。此外，该测试台还将配备一个额外的 1 MW RF 速调管，以测试为 Linac4 开发的不同 352 MHz RF 结构。
In the frame of the SPL (Superconducting Proton Linac) study at CERN, a new 160 MeV proton injector for the CERN PS Booster is presently under development. This linear accelerator (Linac4) would not only be a first step towards a future, multi-MW superconducting linac, but would also improve in the medium term both the beam availability and beam quality for CERN’s proton users. Within the framework of the Linac4 study and with the support of the EU funded Joint Research Activity HIPPI (High Intensity Pulsed Proton Injectors), a 3 MeV test stand is under construction at CERN. This test stand will explore some of the most critical issues of the linac, such as the beam dynamics at low energy, with special emphasis on the chopper line that has been designed to generate the required time structure of the beam, to clean the beam halo, and to match it to the subsequent RF structures. In this context, a new Beam Shape and Halo Monitor is under construction. The beam acceleration will be performed by an RFQ that is being developed in France within the IPHI collaboration between CEA and CNRS. Moreover, the test stand will be equipped with an additional 1 MW RF klystron to test different 352 MHz RF structures that are being developed for the Linac4.
