Scientific paper

We have imploded a 17.5 mm diameter 120 tungsten wire array weighing 450 microgram/cm onto a 4 mm diameter silicon aerogel foam weighing 650 microgram/ cm, using the pulsed power driver SATURN. A peak current of 7.5 MA drove a 50 nsec implosion. The tungten strikes the foam with a 50 cm/microsecond implosion velocity. Radiation temperatures were measured from the side and along the axis with filtered x-ray diode arrays and evidence of radiation trapping by the optically thick tungsten will be presented. The pinch is stable and uniform to less than a 1 mm diameter as measured by time-resolved x-ray framing cameras. Radiation temperature in the foam reaches 140 eV before the main radiation burst or stagnation. *This work supported by the U.S. Department of Energy under Contract DE-AC04- 94AL85000.
