Abstract
As mentioned earlier in the book, two forms of multipacting are distinguished in RF devices: one-point and two-point multipacting. Sometimes these are called one-surface and two-surface multipacting, respectively. One-point multipacting (we will call it MP1 in the following) is characterized as follows: (i) the electrons are emitted from and returned to the same surface and (ii) the time between surface impacts is an integer number of RF periods. In the case of two-point multipacting (MP2), the electrons are oscillating in a cavity in such a manner that they hit the surface – typically of the opposite cavity walls – after an odd number of half periods (1/2, 3/2, 5/2, …).
