Title:	Ion beam driven HEDP experiments at HIFS-VNL
Abstract:	Intense beams of heavy ions are capable of delivering precise and uniform beam energy deposition, with the capability to heat volumetric samples of any solid-phase target material to high energy density. The WDM conditions are achieved by combined longitudinal and transverse space-charge neutralized drift compression of the ion beam to provide a hot spot on the target with a beam spot size of about 1 mm. Initial experiments use a 0.3 MeV, 30-mA K+ beam from the NDCX-I accelerator to heat foil targets such as Au, Pt, W, Al and Si. The NDCX-1 beam contains a low-intensity uncompressed pulse up to >10 µs of intensity ~0.4 MW/cm2, and a high-intensity compressed pulse (FWHM 2-3 ns and fluence ~4 mJ). WDM experiments heat targets by both the compressed and uncompressed parts of the NDCX-I beam, and explore measurement of temperature, droplet formation and other target parameters. Future plans include target experiments using the NDCX-II accelerator, which is designed to heat targets at the Bragg peak using a 2-3 MeV lithium ion beam. *This work was performed under the auspices of the U.S Department of Energy by Lawrence Livermore National Laboratory under Contract DE AC52 07NA27344, and by the University of California, Lawrence Berkeley National Laboratory under Contract DE-AC02-05CH11231.
