摘要：

The characteristics of wide-aperture discharge in helium have been studied for a cathode diameter of 19.5 cm and a cathode-grid anode distance of 3 cm. It is established that the properties of discharge in this system are substantially different from those of a usual abnormal discharge. The difference is manifested in the bending of current-voltage characteristics, their pronounced dependence on the helium pressure, a nonmonotonic dependence of the electron beam generation efficiency eta on the discharge voltage U, and an anomalously high efficiency (eta approximate to 100%) in the range of U approximate to 350-1000 V.
