We have been investigating surface discharges as xuv photon sources for in-situ cleaning and preionizing of anode surfaces in light-ion-fusion accelerators. In these experiments the surface discharge was formed by discharging a capacitor bank across a spark gap which consisted of two copper electrodes attached to an insulator and facing each other across a 5.5-mm gap. The surface discharge and its power feeds were constructed in a stripline configuration to minimize system inductance. When the surface discharge was driven by a 2.9-..mu..F, 45-kV capacitor bank, the peak current thru the discharge was /sup -/250 kA. When driven at these levels, a single discharge radiated with a peak power of over 80 megawatts of 10-to-70 eV photons and had a total xuv output energy of 60 Joules per pulse. The xuv illumination of the anode on Sandia's PBFA-I Accelerator significantly improves the diode impedance characteristics.
