重离子加速器在运行过程中,束流强度可以说是其最主要的参考参数,有一个反映加速器带电离子束流大小主要都是通过这个参数来体现的。而非常微小的电流源,可以用来对束流进行等效。因为在运行过程中一般要对不超过10-12A的电流去监测区分,所以为了使得测量的精度能够达到要求,需要测量电路使用一些特殊的技术,在其设计过程中一般采用特制的电子元件、进行全新的电子设计,甚至会用到特制的材料。本文实现了加速器束流测量系统的核心——束流测量控制器的设计,在其设计过程中主要以微处理器MSC1210为核心进行开发设计。现在,重离子加速器中已经开始使用该系统,加速器运行和物理调试人员的工作强度已经得到了很大的缓解,而且加速器束流传输效率也进一步得到了很大的提升。
Heavy ion accelerator in operation, the beam intensity can be said to be its most important reference parameters, there is a reflection of accelerator ion beam size are mainly reflected by this parameter. The very small current source, can be used to beam equivalent. Because in the operation of the current to no more than 10-12A to monitor the distinction, so in order to make the measurement accuracy to meet the requirements of the measurement circuit to use some special techniques, in the design process generally use special electronic components, New electronic design, even using special materials. In this paper, the design of the beam current measurement controller, which is the core of the accelerator beam current measurement system, is mainly developed and designed with the microprocessor MSC1210 as its core. The heavy ion accelerator has now begun to use the system, accelerator operation and physical commissioning personnel work intensity has been greatly alleviated, and accelerator beam transmission efficiency has also been greatly improved.
