Calorimetric measurements of space distribution energy stream of plasma, formed Hall discharge in channel with metal walls

Summary form only given, as follows. This work is devoted to a research of space distribution of energy of the plasma stream formed in an extended metal channel with crossed electrical and magnetic fields and closed drift of electrons. The distinctive feature from existing accelerators of plasma is the use of a porous anode, through which the working substance (Ar, Xe) come in the digit channel. The availability of a uniform stream of working substance on theoretical evaluations should ensure flat, not missing plasma stream on a withdrawal from a accelerator. For monitoring this request the original technique of calorimetric measurements of a stream of accelerated particles including ions and fast neutrals, obtained in an outcome resonance charge exchange was used. On a path of the stream the target 150*150 mm/sup 2/ from a Ti-foil was installed (= 100 microns, which has very low thermal conductivity). The use of an "AGA Thermovision-782" allowed us to receive space distribution of energy of a plasma jet generated by the accelerator. The obtained outcomes confirm a radial and azimuthal homogeneity of the plasma stream. The radial distributions of temperature on the Ti-target are obtained. It is that the decrease of an average angle of a divergence of shown, a stream on length of 150 mm from 40/spl deg/ up to 15/spl deg/ happens to magnification of a power from 200 up to 800 W. In addition the efficiency of process acceleration of heavy particles is changed from 0.4 up to 0.52.
