Research Abstract

1.Research for diagnostics of implosion
(1) The CT camera for laser produced plasma using imaging plate has been developed, with 40-50mum spatial resolution, 64*64pixels, 64 gradation, 45 directions achieved.
(2) To optimize the CT camera, laser triggered microfocus X-ray source was developed. In it the effect of the laser trigger and the X-ray source image were obtained.
(3) Inverse Radon transform was evaluated to be suitable for laser fusion system. Combined with the Radon transform, the 3-D reconstructed image of radiated X-ray intensity distribution was obtained by the CT camera.
(4) Neutron flux was found detectable by the imaging plate. The minimum sensitivity of the imaging plate was evaluated 5.3*10^8n/cm^2. Prior to the neutron Emission-CT,neutron Transmission-CT was achieved with 11*11pixels-5 directions.
2.CT for pellet diagnostics
(1) Metal coat is necessary to fabricate a multi-layred pellet. By the application of the vacuum evaporation feed-through-collar, we achieved fine Ni coat with the characteristic of the thickness uniformity more than 99% and relative permeability 15.
(2) For high spatial resolution imaging, we developed two techniques : the deconvolution technique using the system function and the technique to adjust the center of the object. Feasibility of these two techniques was demonstrated experimentally.
(3) In addition, for higher spatial resolution, we developed laser triggered microfocus X-ray source. The effect of the laser trigger and the X-ray source image were obtained.
(4) By the use of a combination of these instrumentation-transmissivity meter, interferometer, fringe shift interferometer, the measurement of wall thichness was enabled with an accuracy of better than 1%.
