The expression of the DC clearing electrodefield is derived by the conformal transformation method. The influence on the beam parameters by DC clearing electrode fields is analyzed.
Not concerning the influence of electron on field, the theoretical analysis of electron movement in MILO is made under the condition of planar electrode approximation.
在不考虑电子本身对场影响的前提下，我们采用平板近似对MILO装置中电子的运动规律进行了解析推导。
