引入了两个不同的参数来定量描述束晕,两者都基于粒子分布的矩。其中一个参数是空间光晕形成的度量,之前由 Wangler 和 Crandall 定义,称为轮廓参数。第二个参数依赖于运动学不变量来量化相空间中的晕圈形成;我们称之为光环参数。轮廓参数可以根据实验光束轮廓数据来计算。晕参数提供了理论上更完整的相空间晕描述,但很难通过实验获得。
Two different parameters for the quantitative description of beam halo are introduced, both based on moments of the particle distribution. One parameter is a measure of spatial halo formation and has been defined previously by Wangler and Crandall, termed the profile parameter. The second parameter relies on kinematic invariants to quantify halo formation in phase space; we call it the halo parameter. The profile parameter can be computed from experimental beam profile data. The halo parameter provides a theoretically more complete description of halo in phase space, but is difficult to obtain experimentally.
