“…These findings of [9,12,19] contradict to the value E/N = 15 Td determined for a gas-discharge plasma in a HgBr 2 /Ne mixture [11]. According to [11], more than 90% of the DBD excitation voltage was applied to the quartz tube surrounding one of the electrodes. It seems unusual that less than 10% of the input voltage was applied to the plasma.…”

“…Therefore, the working medium was considered as consisting of two subsystems, electrons and molecular species (HgBr 2 , HgBr(B), HgBr(X), Br, Hg, and Br 2 ). The electron-energy distribution functions (EEDFs), ( ) ε f , were calculated for di electric barrier discharges (DBDs) in different mixtures including HgBr 2 /He [9], HgBr 2 /N 2 /He [8] HgBr 2 /Kr/He [12], and HgBr 2 /Ne [11]. In most cases, the logarithms of the EEDFs decreased approximately linearly with increasing ε from 0 to 25 eV.…”

“…These lamps are attractive due to their narrow-band short-wavelength emission suitable for intense illumination of large areas. In this paper, we study a mercurybromide dielectric-barrier-discharge (DBD) lamp related to excilamps [7][8][9][10][11][12]. The blue-green radiation of this lamp can find applications in scientific research, biotechnology, photonics, medicine, and can also be used to manufacture gasdischarge display panels [8].…”

“…In the DBD lamps of [7,10,11], gaseous mixtures were excited by sequences of two or three pulses of the current and, respectively, the HgBr emission had two or three peaks. The amplitude of the first emission peak was noticeably lower than the amplitudes of the second and third peaks.…”

In a nonequlibrium plasma of a gas-discharge HgBr lamp, the terminal electronic state of the HgBr(B-X) radiative transition with a peak wavelength of 502 nm remains populated for a relatively long time and is repeatedly excited to the B state in collisions with plasma electrons. This transfer of the HgBr molecules from the ground state X to the excited state B is the main mechanism of formation of the light-emitting molecules especially when the lamp is excited by double current pulses. According to our simulations, due to the electron-induced transitions between HgBr(X) and HgBr(B), the output characteristics of the DBD lamp operating in a double-pulse regime are better than those of the lamp operating in a single-pulse regime. In the considered case, the peak power is calculated to increase by a factor of about 2 and the lamp efficiency increases by about 50%.

“…The working mixture in the atmospheric pressure barrier discharge was excited by a power supply with a pulse-periodic output voltage with the possibility of frequency tuning in the range of 1…20 kHz and the amplitude of voltage pulses within 10…30 kV. The research methodology and the research itself were carried out on an experimental setup, which was described in detail in the article [15].…”

The results of studies of the optical characteristics and parameters of DBD (dielectric barrier discharge) plasma on a mixture of mercury dichloride vapor, neon are presented. The following functions were established: EEDF, transport characteristics, specific discharge power losses on electronic processes, electrons’ concentration and temperature, rate constants for elastic and inelastic electron scattering on components of the working mixture, depending on the E/N.

A kinetic model of the working medium of a discharge excilamp on the B-X transition of mercury bromide, HgBr, excimer molecules has been proposed. The model explains the nonmonotonic dependence of the excilamp radiation intensity on the partial pressure of mercury dibromide molecules by the attachment of electrons to these molecules. HgBr(X) molecules were found to transit into the HgBr(B) excited state due to their collisions with high-energy electrons, thereby improving the excilamp characteristics. K e y w o r d s: excilamp, gas discharge plasma, kinetics, excimer radiation, mercury halides.
