Electron Beam at Intermediate Pumping Rates
نویسنده
چکیده
XeF( C --* A ) laser radiation has been produced in a fivecomponent gas mixture excited by a coaxial electron beam with an intermediate pulse length ( 175 ns) and pumping rate ( 1 MW/cm'). The laser output energy was 215 mJ from an active volume of 157 cm3 (1.4 J / L ) at a total gas pressure of 8 bar corresponding to an intrinsic

Spectral Line Competition in a Coaxial Electron-Beam- Pumped High Pressure Ar/Xe Laser
In order to study the kinetic mechanism of the e-beam pumped Ar/Xe laser, the temporal profiles of individual laser lines during multiline oscillation have been measured as a function of power deposition (1-12MW/cm 3) and gas laser pressure (2-14bar) using a short pulse (30 ns) coaxial electron beam as excitation source. It was found that the optimum output energy at each pressure was obtained ...
متن کاملHydrodynamic effects in interacting Fermi electron jets.
We theoretically study hydrodynamic phenomena originating from electron-electron collisions in a two-dimensional Fermi system. We demonstrate that an electron beam sweeping past an aperture creates a pumping effect, attracting carriers from this aperture. This pumping effect originates from the specific electric potential distribution induced by the injected electrons. In the regions near the m...
متن کاملVacuum ultraviolet fluorescence of (Xe b)+ produced in an electron- beam-pumped gas mixture
With a pulsed electron beam a gas mixture of Ar, Xe, and Rb was excited producing (XeRb) + ionic excimer molecules. To study the formation kinetics the (XeRb) + fluorescence pulse was measured as a function of the gas composition and the pumping density. From the observed fluorescence signal decay a value of 6k 1 X 10m3’ cm”/s for the formation rate constant of (XeRb) + from Xe+, Ar, and Rb was...
متن کاملEvaluation of the TiSP3
The purpose of this project was to evaluate the performance and capabilities of the TiSP3, a titanium sublimation pump located at three meters from the interaction point of CESR. Maximum pumping speed obtainable, the optimal number of filament flashes, and the pumping capabilities of a nitrogen-saturated chamber were investigated. Introduction The Cornell Electron Storage Ring (CESR) stores a c...
