摘要

费米实验室和其他能源部高能物理实验室正在研究超大型强子对撞机(VLHC)在后大型强子对撞机时代运行的可能性。目前的超大型强子对撞机设计采用两阶段的方法，其中第二阶段(称为VLHC-2)的质子能量高达100 TeV，峰值光度为2/sup ./10/sup . 34/ cm/sup -2/ sec/sup -1/。质子被引导通过一个周长233公里的大环，环上有10t弯曲磁铁，使用Nb/sub 3/Sn超导体，温度为5k。在这种机器中，光束发出的同步辐射(SR)功率为/ sp1sim / 5w /m/束。然而，其他更小的环和更高亮度的VLHC场景导致SR功率水平超过该值，达到10甚至20 W/m/束。在低温环境中拦截和移除这种能量是一项重大挑战。本文讨论了VLHC-2中的SR问题，并介绍了解决该问题的各种方法。

Synchrotron radiation issues in the VLHC

Fermilab and other DOE high energy physics laboratories are studying the possibility of a Very Large Hadron Collider (VLHC) for operation in the post-LHC era. The current VLHC design foresees a 2-staged approach, where the second stage (referred to as VLHC-2) has a proton energy up to 100 TeV at a peak luminosity of 2/sup ./10/sup 34/ cm/sup -2/ sec/sup -1/. The protons are guided through a large 233 km circumference ring with 10 T bending magnets using Nb/sub 3/Sn superconductor at 5 K. The synchrotron radiation (SR) power emitted by the beam in such a machine is /spl sim/5 W/m/beam. However, other VLHC scenarios with smaller rings and higher luminosity result in SR power levels exceeding this value, reaching 10 or even 20 W/m/beam. Intercepting and removing this power in a cryogenic environment is a major challenge. In this paper a discussion of SR in the VLHC-2, and various approaches to the issue, are presented.
