Source of UV radiation consists of a gas-discharge lamp with helium-containing filling, in which as a means for maintaining the concentration of helium in the lamp, a light-permeable surrounding gas-discharge lamp is used, having a casing connected to a source of a gas helium-containing ...
摘要: We report the experimental results that were received from tunable source of the UV-radiation based on the flash lamp pumped (FLP) dye laser (DL) which operated in pulse periodic mode.. This source. was developed for biological and medical researches in the 260-330 nm range....
A powerful source of broadband UV-VUV radiation is developed on the base of a multichannel sliding discharge. The discharge having a radiating surface of hundreds of cm2 is initiated simultaneously along several dozens of parallel linear channels located close to each other. The design of the disc...
The radiation of discharge plasma was investigated in the nanosecond breakdown of short interelectrode gaps in a nonuniform electric field. Voltage pulses with an incident wave amplitude of 10 kV, a FWHM duration of 1 ns, and a rise time of 200 ps were used. X-ray radiation from the disch...
