Z-Backlighter facility upgrades: A path to short/long pulse, multi-frame, multi-color x-ray backlighting at the Z-Accelerator

Proceedings of SPIE - The International Society for Optical Engineering

Schwarz, Jens S.; Rambo, Patrick K.; Geissel, Matthias G.; Kimmel, Mark W.; Schollmeier, Marius; Smith, Ian C.; Bellum, John; Kletecka, Damon; Sefkow, Adam; Smith, Douglas; Athertona, Briggs

We discuss upgrades and development currently underway at the Z-Backlighter facility. Among them are a new optical parametric chirped pulse amplifier (OPCPA) front end, 94 cm × 42 cm multi layer dielectric (MLD) gratings, dichroic laser beam transport studies, 25 keV x-ray source development, and a major target area expansion. These upgrades will pave the way for short/long pulse, multi-frame, multi-color x-ray backlighting at the Z-Accelerator. © 2011 SPIE.

Above-60-MeV proton acceleration with a 150 TW laser system

Schollmeier, Marius; Geissel, Matthias G.; Sefkow, Adam B.; Rambo, Patrick K.; Schwarz, Jens S.; Atherton, B.W.

Laser-accelerated proton beams can be used in a variety of applications, e.g. ultrafast radiography of dense objects or strong electromagnetic fields. Therefore high energies of tens of MeV are required. We report on proton-acceleration experiments with a 150 TW laser system using mm-sized thin foils and mass-reduced targets of various thicknesses. Thin- foil targets yielded maximum energies of 50 MeV. A further reduction of the target dimensions from mm-size to 250 x 250 x 25 microns increased the maximum proton energy to >65 MeV, which is comparable to proton energies measured only at higher-energy, Petawatt-class laser systems. The dependence of the maximum energy on target dimensions was investigated, and differences between mm-sized thin foils and mass-reduced targets will be reported.
