It was anticipated that the rotation of the plasma within the gun, due to the Lorentz force on the radial current In the longitudinal magnetic field, would improve the azimuthal uniformity 0 the current sbect, The dis- meters of the inner and outer stainless steel electrodes of tho 70 cis long coaxial gun were 3 and 7 cm, respectively. The gas (0.1 ciW2 of drogom) was mdaitted through six openings in the Inner electrode near its center, and the gun was fired by, the 20 kV discharge of a 12 micrafarad capacitor, The plagina gun was located in the uniforn portion of the f leld of a 2.4 a long solenoid, The nagnetic f 1411d rome to Ita maximum strength of up to 8 kOe.1n 28 mIll1sec and subsequently d*cayod exponentially with a time constant of 72 mill1sec, The proceas** taking place within the plasma gun __C~ar,L 1/2 AMN 533. 9, 7 ...... ACC NRi AP6018729 were investigated with the aid of a magnetic probe and by recording the dischtirge current, and the plasmas ejected fron the gun were investigated with an external magnetic probe, a spectrograph, a photowultiplier, a monocImmeter with the aid of which the intensities of different spectrum lines vere displayed oni an oscillograph, and a thermal probe. The rather involved processes that took place within the gun are discussed at some length. The rotation of the plassma gave rise to a magnetic trap within which a considerable portion of the gas was confined. Two plasma bursts were usually produced, but under some conditions It was possible 0 obj*ia only one burst containing some 2 1016 particles at a density of 2.4 r 1011 ca- and 4moving with a velocity of 3 x 104 cm/sec. The purity qf the plawma bursts Increased with Inereaoiag longitudinal viagnetic field stftngth; at a magnetic field strength of 6.4 We there were no lines due to electrode materials in the spectrum, and the lines due to carbon, loxygen, and nitrogen were considerably weaker then in the spectra *9 plams produced without the magnetic field., It is concluded that with the ald of a longltudlmal ~magnetlo field an* can obtain from a coaxial plasma gun pure 1114h enemy planless free of slow and contaminated tells, but at the cost of AnefficlaiA us* of -the mar" stored in the capacitor bank.

Mathematical computations end arguments are introduced, however, that show that if an explooion be it chemical, nuclear, or other, occurs at heights lover than 70--75 kM, the Aock irave can not possibly have any substantial significance in the formation of the gemagnetic disturbance accompanying the explosion. It is concluded, thereforej that the,. Tungusska meteorite shock wave, which occurred at hoightm not micceeding 10 kml played Card 1 /P Itnr. qqn-qAq 7A-CeM~7AH0326-OS" no role it the formation of the magnetic disturbance.
