电子枪单能电子束流强度稳定装置的研制

A beam stabilization apparatus for single energy electron gun

研制了一台电子枪单能电子束流强度的稳定装置。该装置适用于需要连续束流的实验。它控制的流强范围是5nA—5μA。束流强度的稳定度优于2×10^(-2)/h。

A continuous beam intensity stabilization apparatus used in experiments is discussed. The range of beam intensity is 5nA-5μA with a stability of better than 2×10-2/h.
