Calculation of the characteristics of xenon excilamps using a one-dimensional hydrodynamic model

The characteristics of xenon barrier-discharge excilamps have been calculated with the use of a one-dimensional hydrodynamic model in the approximation of a nonlocal electric field. It has been shown that a two-peak mode of operation of the barrier discharge is realized in xenon excilamps. The 172-nm radiation of molecules prevails in the radiation of excilamps; the 147-nm resonance radiation makes no more than 1% of the overall radiation. The radiation intensity of xenon excilamps and their optical efficiency vary inversely on varying the parameters: the radiation intensity of a lamp falls, whereas its optical efficiency increases.
