串列加速器加速的粒子种类繁多,束流强度变化很大(可相差五、六个量级),而能量稳定度可达万分之几。这主要是由于电晕针稳压系统用对数放大代替了静电加速器电晕针稳压系统的线性放大,克服了误差信号与束流强度有关的缺点,大大地压缩了动态范围。该系统结构简单、操作方便,特别在加速各种重粒子、弱束流情况下对能量稳定有很大意义。因而对串列加速器电晕针稳压系统进行研究是必要的。但串列加速器尚未建成,故在ЭГ-2.5静电加速器上作模拟实验研究,并为ЭГ-2.5静电加速器在小束流下稳定运行提供条件。
Tandem accelerator accelerates a wide range of particles, the beam intensity varies greatly (can be a difference of five or six orders of magnitude), and energy stability up to a few thousandths. This is mainly due to the logarithmic amplification of the corona needle stabilization system instead of the linear amplification of the electrostatic accelerator corona needle stabilization system, which overcomes the shortcomings associated with the error signal and beam current strength and greatly reduces the dynamic range. The system has the advantages of simple structure, convenient operation, and great significance for energy stability especially in accelerating various heavy particles and weak beams. Therefore, it is necessary to study the corona pin voltage regulator of tandem accelerator. However, tandem accelerator has not yet been completed, so the simulation experiments on the E-2.5 electrostatic accelerator and the ЭГ-2.5 electrostatic accelerator provided stable conditions under a small beam flow.
