欧洲核子研究中心目前正在研究一种新的H-−直线加速器(LINAC4)。该加速器基于352MHZ和704MHZ的正常导电结构，将向欧洲核子研究中心的PS助推器提供30 mA 160 MeV的H−束流，从而克服目前50 MeV质子束注入时的空间电荷瓶颈。LINAC4被设想为未来2.2GeV超导直线加速器(SPL)的第一级，因此其设计的占空比比PSB所需的更高。本文讨论了大型强子对撞机的设计选择，给出了该装置的布局，并说明了其对大型强子对撞机和欧洲核子研究中心其他用户的优势。提出了以国际合作为主的研发建设战略。
A new H − linac (Linac4) is presently under study at CERN. This accelerator, based on normal conducting structures at 352 and 704 MHz, will provide a 30 mA 160 MeV H − beam to the CERN PS Booster (PSB), thus overcoming the present space-charge bottleneck at injection with a 50 MeV proton beam. Linac4 is conceived as the first stage of a future 2.2 GeV superconducting linac (SPL) and it is therefore designed for a higher duty cycle than necessary for the PSB. This paper discusses the design choices, presents the layout of the facility and illustrates the advantages for the LHC and other CERN users. The R&D and construction strategy, which mainly relies upon international collaborations, is also presented.
