AI总结:

本文提出用 8 GeV 直线加速器替代费米实验室增强器,通过扩展 PIP-II 至 2 GeV 并新建 1300 MHz SRF 段至 8 GeV,将 DUNE 中微子束流功率提升至 2.5 MW 以上。

摘要:

继 PIP-II 800 MeV 直线加速器之后,费米实验室将需要一台从该直线加速器延伸至主注入器(MI)注入能量约 8 GeV 的加速器,以完成费米实验室高强度加速器综合设施的现代化改造。这将使长基线 DUNE 实验可用的中微子产生束流最大化至超过 2.5 MW,并开启下一代强度前沿实验。在本白皮书中,我们为此目的提出一台 8 GeV 直线加速器。该直线加速器由两部分组成:利用 PIP-II 650 MHz 超导射频(SRF)低温模块将 PIP-II 直线加速器延伸至约 2 GeV,随后是由 1300 MHz SRF 低温模块构成的 2→8.0 GeV 直线加速器,后者基于费米实验室开发的 LCLS-II 低温模块。该 8 GeV 直线加速器将融合超导射频技术的最新改进。本文还描述了实现该直线加速器所需的研究工作。

英文摘要:

Following the PIP-II 800 MeV Linac, Fermilab will need an accelerator that extends from that linac to the MI injection energy of ~8 GeV, completing the modernization of the Fermilab high-intensity accelerator complex. This will maximize the beam available for neutrino production for the long baseline DUNE experiment to greater than 2.5 MW and enable a next generation of intensity frontier experiments. In this white paper, we propose an 8 GeV Linac for that purpose. The Linac consists of an extension of the PIP-II Linac to ~2 GeV using PIP-II 650 MHz SRF cryomodules, followed by a 2 -->8.0 GeV Linac composed of 1300 MHz SRF cryomodules, based upon the LCLS-II cryomodules developed at Fermilab. The 8 GeV Linac will incorporate recent improvements in SRF technology. The research needed to implement this Linac is described.
