神龙二号加速器及其关键技术
Dragon-Ⅱ accelerator and its key technology
摘要
神龙二号加速器是一台以MHz猝发率猝发工作的三脉冲直线感应电子加速器。该加速器输出的三脉冲电子束, 相邻两脉冲间最小时间间隔300 ns, 而且可调, 每个脉冲电子束的电子能量18~20 MeV、束流强度大于等于2 kA。当电子束与轫致辐射转换靶相互作用时, 可产生三个强X光脉冲, X光斑点尺寸小于等于2 mm(FWHM), 距靶1 m处照射量大于等于7.74×10-2 C/kg (300 R)。该加速器涉及的主要关键技术包括三脉冲功率源设计、三脉冲强流高品质电子束源的产生、加速场建造、束流传输线设计、轫致辐射转换靶设计、测量与诊断技术等。
Abstract
Dragon-Ⅱ accelerator can provide three pulse electron beams under MHz repetition rate what the performance of each pulse electron beam is 18-20 MeV, 2.1 kA, 60 ns pulse length. Three pulses with adjustable spacing(300 ns minimum spacing) are delivered to the bremsstrahlung targets, generating three 1.7 mm(FWHM) spot size X-ray pulses with a dose of 7.74×10-2 C/kg (300 R) at 1 m. The key technology is analyzed in the accelerator development and the design requirements.
