Abstract :
Summary form only given. We present the results of lifetime and performance measurements made on 4.3 cm bore, 180-cm arc length flashlamps of the size and type we expect to use in the NIF. These flashlamps had 2.5-mm-thick cerium-doped quartz envelopes, electrically insulated bases for mounting, and cathodes doped with low work-function materials to reduce sputtering. We review the results of radiant efficiency and relative Nd-pumping efficiency measurements made with 360- and 500-/spl mu/m pulse lengths and with pulse energies up to 30% of the single-shot explosion energy.
