Keywords:atmospheric pressure gas discharge, photocathode, nano-thickness

By using nano-thickness Au thin film as a photocathode backilluminated from a excimer lamp, a stable gas discharge was operated. Under the conditions of gas, gas flow rate, exciting UV wavelength, and Au thickness, voltage and current characteristics are measured and analyzed.
