摘要:

快速线扫描器今天被认为是高能同步加速器中标准仪器的一部分。他们的使用,以同步加速器工作在较低的能量,库仑散射可以是重要的,横向光束尺寸是大的扩展,介绍了新的并发症,考虑到光束加热的电线,成分的二次粒子簇射和几何考虑在检测设置。在处理这些影响的一个主要问题是,在细碳线的高能初级束的二次放电的创建是很难描述的分析方法。在这里,我们提出了新的结果,从一个完整的蒙特卡罗模拟这个过程产生的信息,在电线,粒子类型和能谱的二次和角度依赖性作为一个功能的主要光束能量的热量沉积。结果被用来推导限制使用线扫描仪在低能量加速器。

英文摘要:

Fast wire scanners are today considered as part of standard instrumentation in high energy synchrotrons. The extension of their use to synchrotrons working at lower energies, where Coulomb scattering can be important and the transverse beam size is large, introduces new complications considering beam heating of the wire, composition of the secondary particle shower and geometrical consideration in the detection set-up. A major problem in treating these effects is that the creation of secondaries in a thin carbon wire by a energetic primary beam is difficult to describe in an analytical way. We are here presenting new results from a full Monte Carlo simulation of this process yielding information on heat deposited in the wire, particle type and energy spectrum of secondaries and angular dependence as a function of primary beam energy. The results are used to derive limits for the use of wire scanners in low energy accelerators.
