ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A high-voltage, short-risetime pulse generator is described. The generator consists of a Marx bank, which produces an initial high-voltage pulse, and a ferrite pulse sharpener that reduces the risetime of the pulse. The generator delivers 70-kV, 350-ps risetime pulses into a 50-Ω load.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A method of triggering multichannel rail-gap switches is described. The method involves producing a glow discharge between a strip of semiconductor material and one of the rail-gap electrodes, the trigger discharge is arranged to extend to the full length of the rail electrode. This trigger technique has been used to trigger a small rail-gap switch and has been shown to be capable of producing high arc densities in the switch. It is expected that the trigger will be suitable for use with long lifetime rail-gap switches.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0649Keywords: 42.55HSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract The role of nitrogen as a buffer gas constituent in an avalance discharge mercury bromide laser has been examined, and it is shown that a change over in excitation from electron impact dissociation of HgBr2 to energy transfer dissociation by excited nitrogen occurs at 1.5%N 2. This is explanable in terms of excitation cross-sections if considerable pumping occurs from excited states of nitrogen which are higher in energy than the metastableA state. When excitation via nitrogen is dominant, a high dischargeE/N value is needed to avoid coupling of energy to unwanted vibrational excitation.Type of Medium: Electronic ResourceURL:
