Fibres experiments in the MAGPIE generator

Summary form only given, as follows. A result of a series of experiments that are being carried out on the MAGPIE generator with carbon, CD2 and D2 fiber loads are presented. Fibers 2 cm long and diameters between 10-200 /spl mu/m are used to study the dynamics of the pinch as well as the initial behaviour of the plasma. Two frames of visible schlieren and interferometry are used to investigate the evolution of the coronal plasma and the growth rate instabilities. In carbon fibers was detected the presence of instabilities as early as 10 ns. Comparison with CD2 and D2 fibers are presented. The dynamics of the hot spot is also studied with both a 4-frame camera and an X-ray streak camera. Movement or bifurcation of hot spots was detected and spatial correlation with optical bright spot was found. The hot spot behaviour in fibers with different diameters is discussed. Hard X-ray emission and high energy electron beams are detected with a combination of plastics scintillator-photo multipliers. A disruption mechanism responsible of such high energy emission is discussed. Time resolved neutron emission is detected with plastics scintillators and total neutron yield is measured with silver activated counter. Measurements in D2 fibers is presented.
