Abstract

An electron-beam energy recovery system was experimentally investigated using a multistage electron collector designed by a numerical simulation. In our previous experiments, the potential of each electrode was provided through a voltage divider of several hundred megaohms resistance. Experimentally, it was observed that a part of the beam currentwas lost to ground through the resistance, and inferred that the electrostatic effect of the electrodes was changed from the initial operating condition. In order to overcome the drawback of voltage divider resistance, two high-voltage power supplies have been provided for the electrodes, and the charge collecting electrodes have been kept at a little higher potential than that of the cathode by using a battery. Therecovery currents of the system have been directly measured by an ammeter. The maximum charge recovery efficiency of the collector was almost 100% with a beam current of 0.2 mA. It was, however, seen that thisefficiency reduced to 73% for a beam current of about 0.85 mA due to the secondary emission. The maximum energy recovery efficiency, 74%, was calculated for 0.2 mA beam current, and this efficiency was reducedto 58% for a beam current of 0.85 mA. (C) 1998 American Institute of Physics.
