Vacuum ultraviolet fluorescence of (Xe b)+ produced in an electron- beam-pumped gas mixture
نویسندگان
چکیده
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 determined.

Vacuum ultraviolet transitions from rare-gas alkali ionic excirners (XeRb)+ and (KrRb)+ by electron beam excitation
Vacuum WV fluorescences from ionic rare-gas alkali excimer molecules were observed by electron beam excitation. A gas mixture of xenon or krypton with a hot vapor of rubidium was excited to obtain a diffuse emission band centered at 164 nm from (XeRb) + and 133 nm from (KrRb) + molecular ions. The observed emission bands are assigned to the 2*2 ’ + 1 ‘Z + transition of (XeRb) + and (KrRb) + , r...
متن کاملInfrared Fluorescence of Xe2 Molecules in beam–excited Xe Gas at high Pressure
We report experimental results of proton– and electron–beam–induced near–infrared (NIR) fluorescence in high–pressure Xe gas at room temperature. The investigated wavelength band spans the range 0.7 ≤ λ ≤ 1.8μm. In the previously unexplored range for λ > 1.05μm we have detected a broad continuum NIR fluorescence at λ ≈ 1.3μm that shifts towards longer wavelengths as pressure is increased up to ...
متن کاملSteady-state gain and saturation flux measurements in a high efficiency, electron-beam-pumped, Ar-Xe laser
Flat-top, Ar-Xe laser pulses at 1.73 ,um have been achieved by pumping the laser medium with a constant-current electron beam for pulse durations of up to 2.5 ms. The 220 keV electron beam pumped an active volume of 50X 8X6 cm3 at power loadings of 6-100 W/cm3. Small signal gain, saturation flux, and nonsaturable absorption were determined as a function of Xe concentration, total gas pressure, ...

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 ...
