[en] The SRC two beam Nd glass laser facility with output of up to 40J per beam in 100 ps pulses and 80J per beam in 1.6 ns pulses has been used to study interactions in the critical density region, energy transport in solid targets and compression of spherical targets. Magnetic field generation and ponderomotive force modifications to density gradients have been observed by optical probing using Faraday rotation and interferometry. Electron energy transport has been studied with layered targets. The ablation front plasma parameters and the ablation depth have been recorded for spherical targets and related to numerical modelling of the inhibited thermal transport. The temporal and spatial development of transmission in thin plane polymer film has been used as an indicator of lateral thermal transport. X-ray spectroscopy of compression cores in exploding pusher targets has been refined by new line profile calculations and improved computer fitting methods, and some further results are presented. Dense implosions created by exploding glass shell compression of a high density gas fill have been studied by pulsed X-ray shadowgraphy. 40 references. (UK)
