Title: PERFORMANCE OF A HYDROMAGNETIC PLASMA GUN

PERFORMANCE OF A HYDROMAGNETIC PLASMA GUN The performance of a hydromagnetic plasma gun is discussed which is able to accelerate several liters of hydrogen plasma containing about 5 x 10/sup 13/ protons to a velocity of 1.5 x 10/sup 7/ cm/sec and deposits more than 40% of the electric input energy at its terminals into kinetic energy of the jet. Magnetic probe measurements indicate that the jet can punch its way axially through the 10,000-gauss field of an external solenoid. Mass spectroscopic observations of a collimated sample of the jet shows a proton velocity spread of less than a factor of two. This and other evidence indicates a relatively low temperature of the plasma compared to its kinetic energy (100 ev per proton). (B.O.G.)
