Abstract :
The Trichel pulses induced by a sharp point cathode in liquid argon are discussed. A crude analysis of the phenomena shows that the apparent charge carrier mobility is proportional to the current pulse duration in a given duration range. A very rough estimate of this time qualitatively accounts for its observed variations with the applied voltage in a liquid sample highly purified through the injection of electrons.
