卢瑟福·阿普尔顿实验室正在进行的升级ISIS散裂中子源工作的一个主要组成部分是前端试验台(FETS)。FETS旨在提高直线加速器的亮度,由彭宁离子源、低能束流传输(LEBT)、射频四极杆(RFQ)和中能束流传输(MEBT)组成。它可以作为加速器链的第一部分,提供高达10%的占空比高达60毫安、3兆瓦的H{sup-}束流。光源的电流输出和LEBT的传输是合理的,但在对准方面存在问题,以提供与RFQ接受相匹配的中心光束。已对员额加速进行了改进,以解决此问题。用准直光束进行了测量,以了解螺线管和转向磁铁的行为。将这些结果与模拟结果进行比较,证明了除了离子源和后加速组件可能存在的机械缺陷外,只有在磁场扭曲的情况下才能达成一致。
A major component of work being carried out to upgrade the ISIS spallation neutron source at Rutherford Appleton Laboratory (RAL) is the Front End Test Stand (FETS). FETS is aimed at improving the luminosity of the linac, and consists of a Penning ion source, Low Energy Beam Transport (LEBT), Radio Frequency Quadrupole (RFQ), and Medium Energy Beam Transport (MEBT). It may serve as a first part of the accelerator chain providing a 60 mA, 3 MeV H{sup –} beam up to a 10% duty cycle. The current output of the source and the transmission of the LEBT are reasonable, but there are issues with the alignment to provide a centred beam matched into the acceptance of the RFQ. Improvements have been made to the post acceleration to address this problem. Measurements with a collimated beam have been performed to understand the behaviour of the solenoids and steerer magnets. Comparing these results with simulations proved that, besides possible mechanical imperfections of the ion source and post acceleration assembly, agreement can only be achieved if the magnetic fields are distorted.
