description FIELD: electrics. ^ SUBSTANCE: invention concerns devices for generation of emission, generation of ultraviolet photo impulses with possible amplitude and time adjustment within wide frequency band, particularly from nanosecond long impulses to continuous emission. Device includes sealed bulb with light-transparent outlet port with cathode and anode inside. UV emission sensor is installed outside the bulb close to the port. UV emission source is positioned on light-transparent port inside the deaerated bulb. Focusing electrode, accelerating electrode and turnoff electrode are positioned in sequence between anode and cathode, so that anode, and focusing and accelerating electrodes are connected to high voltage source, while turnoff electrode is connected to turnoff voltage source, cathode is earthed to device case over cathode current control circuit, and cathode heater is connected to cathode heating source. UV emission sensor, high voltage source, turnoff voltage source and cathode power source are connected to controller processor. Large-band ion crystals (such as CaF2, BaF2, BeO etc.) or heterostructures based on III-N compounds (such as AlGaN etc.) can be applied as UV emission source. ^ EFFECT: device for generation of ultraviolet photo impulses, enabling reproduction of signals of various physical processes and phenomena accompanied by ultraviolet irradiation. ^ 3 cl, 1 dwg
