Abstract
An improved electron discharge device comprises an evacuated envelope having therein a photoemissive cathode for providing photoelectrons in response to radiation incident thereon, an electron multiplier, including a primary dynode spaced from the cathode, and a focusing assembly disposed between the cathode and the multiplier. A thermionic electron control plate is disposed between the focusing assembly and the multiplier to prevent thermionic electrons from the focusing assembly from impinging on the primary dynode, while permitting the passage of photoelectrons to the primary dynode. The control plate overlies the primary dynode and is contiguous therewith.
