Abstract

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 cm 2 is initiated simultaneously along several dozens of parallel linear channels located close to each other. The design of the discharge electric circuit allows a remarkably fast energy deposition into plasma: up to 4 kJ during 1.5 μs. Absolute measurements of discharge VUV radiation are performed by the method of spectrally selective dynamic actinometry. The total photon flux produced by the source within the spectral range of 120–200 nm reaches 1026 photons/s.
