Abstract :
Summary form only given, as follows. The systems with compression of magnetized heated plasma (MAGO/MTF) are promising regarding the achievement of the thermonuclear fusion threshold. A version of this system has been realized in VNIIEF where a dense high temperature DT-plasma was obtained with the lifetime of some microseconds, being a source of high-power neutrons and X-ray pulses. The research method of spatial-temporal parameters in the soft X-ray generation plasma region, which is formed in the discharging camera of the MAGO-system, has been developed for diagnostics. The method is based on the soft X-ray plasma image formation with the help of a pinhole camera and its consequent conversion to an optical image. Optical plasma image registration is made with the use of an electron optical multi-frame recording system. For the first time in the conditions of the MAGO explosive experiments the two-dimensional plasma image for three sequential intervals of discharge, corresponding to maximum soft X-rays yield was obtained. The position, shape and typical sizes of the plasma region are determined. The evolution of the described method for plasma parameters research in MAGO/MTF experiments is seemed to be very perspective.
