Abstract: FIELD: material technology; chemical industry; mechanical engineering; propulsion engineering. 
     SUBSTANCE: method allows getting of dense high-temperature plasma. According to the first version o the method, gas is subject to super adiabatic heating combined with compression in ballistic installation. Procedure goes in two steps separated by crossover step. Two pistons compress gas - main continuous one and additional one provided with hole for gas crossing-over. Additional piston is made for tying with main piston. After the first step of compression is over and total amount of gas is crossed over into space ahead additional piston, both pistons are fixed together and second step of compression is carried out while both pied pistons move to end of cylinder. Additional piston is placed close to end of cylinder at distance of 0,3-0,4 its length. According to the second version, gas is subject to super adiabatic heating while being pressed by two continuous pistons during two steps separated by crossover step. Gas is subject to compression by free pistons in cylinder of ballistic installation divided to two parts by partition having crossover hole with valve. First pistons disposed at the end of cylinder and the second one - close to partition at other side of cylinder. During first step when hole in partition is closed, gas is heated by compressing till pressure of P 1  is reached when first piston moves in the direction of partition. After that or simultaneously with compression the total amount of heated gas is crossed over to second part of cylinder of ballistic installation and the first piston is displaced. After crossover is finished, the second step of compression is carried out be means of second piston at closed hole in partition till reaching pressure of P 2 . Gas is compressed during first and second steps of procedure till reaching maximal pressure of P m = P 1=  P 2 , which is defined by strength of construction of ballistic installation. Cinematically tied pistons compress gas. 
     EFFECT: maximal temperature of heating can be achieved without additional increase in pressure or in degree of compression.
