This paper presents experimental studies of excilamps based on xenon dimers excited by a barrier discharge. Their characteristics in the natural-cooling and forced-cooling regime are investigated. It is established that the limitation of the power density of the radiation at high excitation powers is associated with the cooling efficiency of the excilamp radiator. It is shown that the radiation power density of sealed excilamps based on xenon dimers can reach 100 mW/cm2 in the quasi-steady-state regime. A circuit for an excilamp-excitation source and for the design of the excilamps is presented, along with a technique for calculating the excitation energy and power of barrier-discharge excilamps.
