摘要
通过求解电子冷却系统中冷却段漂移管区的强流电子束产生的空间电荷场,研究了电子束空间电荷效应对电子温升的影响。结合HIRFL CSR电子冷却系统的典型参数,得到了电子在自身空间电荷场和纵向螺线管磁场组成的交叉场作用下产生的漂移速度和由此引起的附加温度大小,并指出减小电子束空间电荷效应的方法。
There exists the gradient distribution of radial electron velocity due to space charge effect of intense electron beam, and this influences significantly the cooling efficiency. By analysis of the space charge field of intense electron beam in the cooling section of electron cooler system, the variations of electron beam velocity are given. In addition, electron gets the transversal drift velocity and meanwhile causes an additional temperature rise in this crossing field produced by space charge field and longitudinal solenoid field. Using the typical parameters of HIRFLCSR ecooler system, some important conclusions have been drawn.
