The progress of the construction of very large laser facilities LMJ and NIF enables the prediction of inertial fusion achievement. These facilities will open new fields for research: the high energy density physics. Pressures of several 100 Mbars and

We present an x‐ray detector with a high sensitivity in the 1–20 MeV x‐ray range. This device consists of a scintillator coupled with a microchannel plate image intensifier tube working in the visible range. The performance of the hard‐x‐ra

Two diagnostics for the study of hard x‐ray emission produced by plasmas during inertial confinement fusion experiments, are described: (i) a hard x‐ray spectrometer to measure the high‐energy tail of the spectrum, with eight spectral bands in

We present a high gain x‐ray image intensifier with high sensitivity in the 1 MeV x‐ray range and a good spatial resolution developed in order to improve the radiographic detection in our experiments. In particular the gold photocathode and MCP t

The authors present the shock compression response of a 2-mm*2-mm active area PVF2 gauge. The shock response was studied both on a phi 30-mm powder gun and with a plane wave lens of high explosives coupled to ceramic attenuators. The results obtained

The dynamic behavjour of the PVF 2 gauge designed and produced by CEV-M * has been investigated both by CEV-M * and CEG ** under plane wave loading. In the range 0-100 kbar, the accuracy on the measured stress is ± 5% and the gauge can be used for b

A vertical shock tube built for the study of Rayleigh‐Taylor instability induced turbulent mixing is described. The first results obtained by schlieren visualization concern the interaction between a Mach 1.45 shock wave and subsequent reflected wa

Semitransparent S1 photocathodes have been developed on a low‐resistivity SnO2 layer for streak camera image converter tubes. The 50‐Ω/⧠ resistivity combined with good photocathode sensitivity prevents parasitic effects and provides an efficie

Improvement in laser‐plasma analysis makes it necessary to perform accurate calibration in the soft x‐ray range. For this purpose we have modified a plasma focus device (27 kJ, 40 kV, and 400 kA) in order to enhance its soft x‐ray emission: A h

For x-ray calibration of detectors used on laser created plasma experiments we have developed and characterized two kinds of sources : classical continuous x-ray sources operating at 1.8 keV and 5.4 keV and a pulsed source obtained by modifying a pla
