Opis:
In the present paper, the review of the basic results obtained at the Laboratory of Optical Radiation at High Current Electronics Institute SB RAS during 2007-2009 years is presented. Efficient radiation of $Ar_{2}$, $Kr_{2}$, $Xe_{2}$, $KrBr^\ast$, $KrCl^\ast$, $XeI^\ast$, $XeBr^\ast$, $XeCl^\ast$, $Cl_{2}^\ast$ molecules and I atoms was obtained in rare gas or in rare gas-$Br_{2}$ ($Cl_{2}$, $I_{2}$) mixtures. Study of radiation parameters and lifetime period of the manufactured barrier discharge excilamps has been performed.

Opis:
Influence of two different laser beam profiles, the Gaussian and the Π (top hat) profile on the resonance line widths and amplitudes in the Hanle electromagnetically induced transparency was studied. The laser beam propagates through the vacuum Rb glass cell. Studies were done at $D_1$ line for the open $\text{}^{87}Rb:$ $F_{g}$=2 → $F_{e}$=1 transition. Hanle electromagnetically induced transparency was measured for the two beam profiles with the same total power and beam diameter and experimental results showed that Gaussian and the top hat profiles give different amplitudes and widths of the Hanle resonances. Resonances obtained from the top hat laser beam profile have lower amplitudes and higher line widths.

Opis:
The results of optical spectroscopic (UV-Vis, absorption, and emission), acoustic (sound velocity of precursor solutions, the solvation numbers of ions in these solutions), and positron annihilation of glasses are presented and discussed for silica glasses obtained by the alcoholic sol-gel technique, doped with selected lanthanides and with some addition of ethylene glycol. The aim of these investigations was the determination of the local structure of glass close to lanthanide ions and its influence on the optical properties of the material. The results show that the existence of alcohol-glycol solvates in glasses decrease the number of empty voids in its structure as well as the size of the remaining ones. One can suppose that this is caused by cooperative interactions of glycol molecules with the network of hydrogen bonds of the glass.

Opis:
The presentation will give an overview of the design, construction, test and reliability of a solid state switch assembly used for magnetic forming applications. In 2005 a prototype of a reverse conducting semiconductor switch for 210 kA at 100 μs damped sine wave discharge and 21 kV dc was designed to be used in an experimental system at the Fraunhofer Institute at Chemnitz (Germany). The aim was to show the industry that semiconductors can be used for this type of applications. Precautions in the design stage have to be taken to reach high operational lifetime. The presented prototype switch was designed for an expected lifetime of 20 000 shots under nominal and 1 000 shots under short circuit conditions of 420 kA. After successful commissioning, further tests were done on separate semiconductor devices to verify under which conditions the lifetime could be increased to several million shots for the given application. For this verification, ABB has done extended device tests over more than one million shots and the wafers were analysed. The results of the reliability test are part of this presentation. It will be concluded that proper designed solid state switches are economically feasible, free from maintenance and despite higher initial cost are more reliable and superior to any other technology existing today.
