Electron-beam-ignited, high-frequency-driven vacuum ultraviolet excimer light source
T. Dandl, H. Hagn, T. Heindl +3
Transformation of a table-top electron beam sustained 2.45 GHz RF discharge in rare gases into a self burning discharge has been observed for increasing RF-amplitude. Thereby, the…
Electron-beam-sustained discharge revisited - light emission from combined electron beam and microwave excited argon at atmospheric pressure
T. Dandl, H. Hagn, A. Neumeier +2
A novel kind of electron beam sustained discharge is presented in which a 12keV electron beam is combined with a 2.45GHz microwave power to excite argon gas at atmospheric pressure…
Attenuation of vacuum ultraviolet light in liquid argon
A. Neumeier, M. Hofmann, L. Oberauer +6
The transmission of liquid argon has been measured, wavelength resolved, for a wavelength interval from 118 to 250 nm. The wavelength dependent attenuation length is presented for…
Intense Vacuum-Ultraviolet and Infrared Scintillation of Liquid Ar-Xe Mixtures
A. Neumeier, T. Dandl, T. Heindl +7
Vacuum ultraviolet light emission from xenon-doped liquid argon is described in the context of liquid noble gas particle detectors. Xenon concentrations in liquid argon from 0.1 pp…
Intense Infrared Scintillation of Liquid Ar-Xe Mixtures
A. Neumeier, T. Dandl, T. Heindl +9
Intense infrared (IR) light emission from liquid Ar-Xe mixtures has been observed using 12 keV electron-beam excitation. The emission peaks at a wavelength of 1.18 m and the hal…
Ion-beam excitation of liquid argon
M. Hofmann, T. Dandl, T. Heindl +7
The scintillation light of liquid argon has been recorded wavelength and time resolved with very good statistics in a wavelength interval ranging from 118 nm through 970 nm. Three…
