| Popis: |
The systems with compression of preheated magnetized 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 a lifetime of few microseconds, being a source of high power neutron and X-ray pulses. For diagnostics a research method for spatial-temporal parameters in the soft X-ray generation plasma region, which is formed in the MAGO chamber, has been developed. The method is based on 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 optics multi-frame recording system. For the first time for the conditions of MAGO explosive experiments the two-dimensional plasma images for three sequential intervals of discharge, corresponding to a maximum soft X-ray yield was obtained. The position, shape and typical sizes of the plasma region are determined. The development of the method for plasma research in MAGO/MTF experiments seems possible. |
