INFLUENCE OF ACCELERATING GAPS ON EMITTANCE GROWTH IN A LINEAR INDUCTION ACCELERATOR
-
摘要: 文中用解析方法计算了直线感应加速器加速间隙对发射度的影响。考虑了存在轴向引导磁场,加速电场,束流分裂以及多个加速间隙的作用。这种解析方法也适用于射频直线加速器的情形。Abstract: Eemittance formulas of a beam in a linear induction accelerator, in consideration of the guiding magnetic field, self electro -magnetic field, accelerating field and the field induced by the accelerating gaps for a uniformly distributed beam are derived.
The conclusion is that the phenomena of beam break up for a 20MeV electron beam is not serious the linear wake field case.-
