      Electron emission from sharp points in liquid argon 

      Bressi, G.; Carugno, G.; Ptohos, Fotios (1991)
      Electron charge injection from a point electrode in gaseous and in liquid argon has been observed and its characteristics studied. In liquid argon, as we have observed, the charge dependence on applied voltage is governed ...

      Electron lifetime detector for liquid argon 

      Carugno, G.; Dainese, B.; Pietropaolo, F.; Ptohos, Fotios (1990)
      A method has been developed for a fast and reproducible measurement of the electronegative contamination of liquid argon. The method is based on the transport of electrons extracted by a NdYag UV laser beam from a metallic ...

      A study of the electron image due to ionizing events in a two-dimensional liquid argon TPC with a 24 cm drift gap 

      Bonetti, S.; Braggiotti, A.; Buckley, E.; Campanella, M.; Carugno, G.; Cecchet, G.; Cennini, P.; Centro, S.; Ciocio, A.; Cittolin, S.; Dainese, B.; Ferro-Luzzi, M.; Gasparini, F.; Gonidec, A.; Manfredi, P. F.; Meroni, E.; Muñoz, R.; Perreau, J. -M; Pietropaolo, F.; Ptohos, Fotios; Ragusa, F.; Rossi, P.; Rubbia, C.; Schinzel, D.; Schmidt, W. F.; Seidl, W. (1990)
      We have tested a liquid argon time projection chamber with a novel wire configuration based on electrostatic focussing which allows the realization of a nondestructive detection of the electron image produced by ionizing ...
