一种用于C-ADS低能束流传输线束流强度控制的新型可调限束光阑
A novel adjustable aperture for beam current controlling at China-ADS low energy beam transport line
摘要
Abstract
A novel adjustable aperture is developed for the low energy beam transport line (LEBT) of the ChinaAccelerator Driven Subcritical System (C-ADS). Two relatively rotating mirror-symmetry cores are adopted for the adjustable aperture to scrape unwanted outer particles, improve the beam quality and reduce the beam losses, and most of all, realize continuously tunable beam current and meet the requirement of round beam. The results of simulation and test show that the unwanted outer particles can be cut away and the beam current can be adjusted continuously online within the range of 0 to 10 mA. This device provides a convenient beam tuning method for the proton linear accelerator, which can satisfy the stable and reliable online operation of C-ADS linear accelerator.关键词
