电子冷却装置中,电子束纵向温度是计算冷却力的主要参量之一．当电子与被冷却离子的相对速度很小时,纵向冷却力与离子速度呈线性关系,并且线性区域的宽度与电子束纵向温度有关．通过分析影响电子束纵向温度的主要因素,得到了兰州重离子冷却储存环实验环(CSRe)电子冷却装置中电子束纵向温度的大小．
In the electronic cooling device, the longitudinal temperature of the electron beam is one of the main parameters for calculating the cooling force. When the relative velocity between the electrons and the cooled ions is small, the longitudinal cooling force is linear with the ion velocity, and the width of the linear region is related to the electron beam longitudinal temperature. By analyzing the main factors influencing the longitudinal temperature of the electron beam, the longitudinal temperature of the electron beam in the CSR electronic cooling device of Lanzhou was obtained.
