实验背对背带栅双电离室的构造如图1所示。中心是一带小准直器的铂金片,在它的一面附有~(235)U样品作为公共阴极。与阴极相连接的是一个保护环,其作用是使阴极、栅极间
Experimental back-strap gate double ionization chamber structure shown in Figure 1. The center is a Platinum piece with a small collimator with a sample of ~ (235) U as its common cathode on one side. Connected with the cathode is a guard ring, its role is to make the cathode and gate
