abstract = {This report is an experimental study of the conversion af
laser light into x-rays in a hohlraum target. By these
experiments, the proposed indirect target design for energy
loss measurements of swift heavy ions in a dense plasma has
been explored. The experiments take place at Gesellschaft
für Schwerionenforschung (GSI), Darmstadt, Germany. For the
experiments, the nhelix laser is used. This is a
Nd:YAG/Nd:glass based laser system, wavelength λ = 1064 nm,
pulse length (FWHM) 14 ns and energy EL = 60 − 100 J. The
targets are prepared for determining the optimum parameters
for x-ray conversion. The targets are gold cylinders,
1−1.5 mm of length and outer diameter 1 mm. The inner
diameter is either 500 μm or 700 μm. The cylinder is
covered at the x-ray exit window with either a 0.5 μm
polypropylene foil or 80−110 nm gold foils. The radiation
leaving the target is characterized using coated Si-diodes
and pinhole cameras. The radiation temperature is determined
and an estimation of the conversion efficiency is given.The
optimum target parameters have been determined to be: target
length L = 1 mm, inner diameter D = 700 μm and foil
thickness d: 80 nm < d < 110 nm. An upper limit of the
radiation temperature is ∼ 10 eV . The conversion
efficiency is estimated to be ≤ $1\%.$ This is reasonable
with the present laser parameters.},
