摘要：
Secondary electron emission is shown to occur at the boundary of the working region of a photocathode when current flows through this region, causing a deviation from the known classical laws of photoemission. It is established that the sensitivity and photoemission threshold of the photocathode depend on the strength of the photocurrent flowing through it.
