The stand includes a shock tube of section (72u72mm 2 ), visualization system of shadow, interferentional and holographic methods, and also equipment for measurement of pressure and shock wave velocity. The arrangement of the devices with designations of its basic elements is shown in Fig.1. The shock tube consists of the high pressure chamber (HPC) - 1 and low pressure chamber (LPC) - 2,3,4,5,6. The HPC and the LPC have accordingly, the lengths 1m and 5.9m, and are separated by the diaphragm 9. LPC is terminated by the experimental dielectrical chamber 7 with optical windows of diameter 100mm and electrical discharge system 25. The shock wave velocity U =700-1100m/s for initial pressure in LPC Ɋ =2- 15Torr.The velocity of shock waves is measured by piezogauges d1, d5, d6 on bases L1 (d 6 - d 5 )=135.5mm and L2 (d 5 -d 1 )=101.5mm; the gauge d1 is placed a distance of 217mm from the center place of the discharge region. Other piezogauges together with the electronic equipment provide: 1) - the measurement of pressure, 2) - discharge start
