On the basis of the precisely recorded 20 neutral krypton (Kr I) line shapes (in the 5s-5p and 5s-6p transitions), we have obtained the basic plasma parameters, i.e., electron temperature (T) and electron density (N) using our line deconvolution procedure in a plasma created in a linear, low-pressure, pulsed arc discharge operated in krypton. The mentioned plasma parameters have also been measu...

The thermally induced order-to-disorder transition of a monolayer of krypton (Kr) atoms adsorbed on a graphite surface is studied based on a coarse molecular-dynamics (CMD) approach for the bracketing and location of the transition onset. A planar order parameter is identified as a coarse variable, psi, that can describe the macroscopic state of the system. Implementation of the CMD method enab...

Clusters of krypton are generated in a supersonic expansion and size selected by deflection from a helium target beam. By measuring angular distributions for different fragment masses and time-of-flight distributions for fixed deflection angles and fragment masses, the complete fragmentation patterns for electron impact ionization at 70 eV are obtained from the dimer to the heptamer. For each o...

The extreme diffusibility of hydrogen, compared with xenon or krypton, may create serious artifacts when it is used to measure local blood flow with a tissue electrode. The errors are greatest when hydrogen is given by intra-arterial slug injection, and when the electrode is within 2mm of another tissue compartment, CSF, or air. These all appear to be a consequence of intercompartmental diffus...

High-temperature implosions are planned for the OMEGA Upgrade experimental program. By using relatively thin shell targets, temperatures much higher than 1 keV at modest compressed densities (1 to 5 g/cm3) are predicted. The goal of this work is to demonstrate that by adding a small admixture of krypton gas (-0.01 atm) to the fuel, the temperature can be conveniently diagnosed through the spect...

The shape and shift of the 535.0 nm thallium line resulting from the photodissociation of thallium iodide perturbed by krypton and xenon were investigated at low densities. The Doppler and collision broadening components of the line shape have been determined. The linear dependence of both the Lorentzian half-width and the shift on the perturbing gas density was found and interpreted in terms o...

The results of experimental studies on the breakdown noble gases (argon and krypton) by terahertz radiation from Novosibirsk free electron laser (NovoFEL) are presented. For first time, thresholds were measured in a wide pressure range (0.2-1.5 bar). Previous experiments to measure THz various carried out for hundreds GHz or at atmospheric pressure. Experimental compared with calculated data us...

A high repetition-rate e-beam pumped Krypton fluoride (KrF) laser has been developed as a prototype of future IFE driver. A combination of power supply with high voltage magnetic switches and e-beam diode cooled by water and self heat-radiation is generating e-beam at 0.5 Hz. Laser oscillation at 1 Hz with output energy over 20 J is expected in near future. Intense short pulse (> 10 J, ~3 ps) h...
