AbstractAbstract
[en] Many of the technical problems of generating a large thin liquid sheet from 0.02 to 0.20 μm thick (3 to 40 μgm/cm2) have been solved. It is shown that this perennial sheet is stable and consonant in dimension. Several ion beam species from the SuperHILAC have been used for evaluation; at 0.11 MeV/n. In one of three modes this sheet serves as an equivalent substitute for a carbon foil. The second mode is characterized by a solid-like charge state distribution but with a varying fraction of unstripped ions. The third mode gives stripping performance akin to a vapor stripping medium. 9 references, 7 figures

AbstractAbstract
[en] A titanium-doped sapphire regenerative dual-amplifier array operating at multi-kHz repetition rates has been developed for synchrotron radiation ultra-fast x-ray applications. The thermal lensing of the crystal in the amplifiers is virtually eliminated by cryogenic cooling of the laser crystal. The output energy of the amplifiers is measured to be greater than 2.6 mJ and the pulse length was compressed to less than 70 fs. The output laser mode is a near perfect Gaussian TEM00 with an M2 factor of 1.02. The performance of the amplifier system is in excellent agreement with theoretical calculation.

AbstractAbstract
[en] We have measured the absorption of x-rays in neon gas in the presence of a strong laser pulse. The femtosecond x-rays were tuned to energies near the neon 1s-3p resonance, and the laser intensity of 1013 W/cm2 was below the intensity required to alone ionize neon. We observed strong modification of the x-ray absorption when the neon was subjected to laser light that was temporally overlapped with the x-rays.

AbstractAbstract
[en] High-resolution K -shell photodetachment measurements of He- giving rise to He+ ions have been performed using a merged synchrotron vacuum ultraviolet photon-ion beam technique. The measurements on this fundamental negative ion display dramatic structure differing substantially, qualitatively and quantitatively, from the corresponding process in neutral atoms and positive ions, owing to the dominance of correlation in both initial and final states of He- . In addition, this experimental investigation provides an unambiguous test of two independent theoretical calculations that report serious discrepancies and shows excellent agreement with one of them

AbstractAbstract
[en] Vibrationally resolved cross section for the valence shell photoionization of N2 and CO has been accurately measured experimentally up to 300 eV. Series of ratios between two vibrational cross sections (v-ratios) are compared to theoretical results obtained from a new ah initio DFT method that includes nuclear motion. It reveals strong oscillations around the Franck-Condon factor which are the fingerprints of double-slit like interferences. To support this point, a simple model (based on the Cohen-Fano formula) will be presented at the conference.

AbstractAbstract
[en] Measurement of absolute cross sections for photoionization of ions has become feasible by merging a well-collimated ion beam with a monochromatic beam of synchrotron radiation. An electron cyclotron resonance (ECR) ion source permits such measurements to be extended to multiply charged ions, and makes possible systematic studies along isoelectronic sequences. The evolution of atomic spectra along such sequences is commonly studied theoretically, but the predictive ability of the theoretical methods remains largely untested. Absolute cross-section measurements are presented for the first three ionic members of the isoelectronic sequence of nitrogen (O+, F2+ and Ne3+)
