Runaway electron preionized diffuse discharges in atmospheric pressure air in point-to-point gaps in repetitive pulsed mode

Summary form only given. At present the sources of UV and VUV spontaneous radiation are vigorously investigated and enjoy wide use in different areas of science and technology. However, the devices developed to date and manufactured by the industry do not satisfy all requirements. For instance, to calibrate spectral instruments and optical elements requires point UV and VUV radiation sources with a radiating volume of ∼1 mm³ and a relatively high pulsed output power (above 1 W). Also of practical interest are the sources with nanosecond pulse duration operating in a pulse-periodic regime.
