摘要：
A new method for measuring the absolute efficiency for electron counting with channel electron multipliers (CEMs) is described. The new method is based on the transient time response of the CEMs to pulsed electron beams. It is especially suitable for CEMs with resistance higher than 100 M Omega and it has been used to determine the absolute efficiency of a B419BL (Mullard) and KPE07 (TUG) CEM for detection of electrons in the energy range 50-1500 eV.
