费米实验室超导束实验装置机器保护系统的研制

Development of a machine protection system for the Superconducting Beam Test Facility at Fermilab

A. Warner, L. Carmichael, M. Church, R. Neswold

摘要:

费米实验室目前正在建设的超导射频束测试设施将产生能够在异常加速器脉冲的情况下损坏加速结构和束线真空室的电子束。该加速器的设计能力为每个宏脉冲可产生多达3000个聚束,重复频率为5Hz,束流能量为1.5 GeV。在束团电荷为3.2nC时,它能维持72KW的平均束流功率。在全强度下操作将在铌材料中沉积足够的能量以接近2500 °C的熔点。在早期阶段,仅安装了3个低温模块,该设施将能够产生810 MeV的电子束能量和接近40 KW的平均束功率。在任何一种情况下,都需要一个强大的机器保护系统(MPS)来减轻由于这种大的损坏潜力造成的影响。本文将描述正在开发的MPS系统,系统要求和考虑中的控制问题。

英文摘要:

Fermilab's Superconducting RF Beam Test Facility currently under construction will produce electron beams capable of damaging the acceleration structures and the beam line vacuum chambers in the event of an aberrant accelerator pulse. The accelerator is being designed with the capability to operate with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 1.5 GeV beam energy. It will be able to sustain an average beam power of 72 KW at the bunch charge of 3.2 nC. Operation at full intensity will deposit enough energy in niobium material to approach the melting point of 2500 °C. In the early phase with only 3 cryomodules installed the facility will be capable of generating electron beam energies of 810 MeV and an average beam power that approaches 40 KW. In either case a robust Machine Protection System (MPS) is required to mitigate effects due to such large damage potentials. This paper will describe the MPS system being developed, the system requirements and the controls issues under consideration.
