Investigating laser-induced ionization of purified liquid argon in a time projection chamber
Abstract
A UV-wavelength laser beam was used to ionize a purified liquid argon medium in a time projection chamber environment, and for the first time, to our knowledge, ionization signals corresponding to ionization electrons were measured in the particle time projection chamber resulting in a laser calibration. Furthermore, the mechanism of the complicated ionization process has been postulated.
