Abstract : Part of a 30-nanosecond, 30,000-ampere, 3.5-million-electron-volt pulse has been extracted from a pulsed X-ray machine and has been projected into an ionized medium formed by a 33,000-ampere, 7,000-volt, pinched discharge in argon. The beam of relativistic electrons traveled more than 23 centimeters without space charge blowup even though similar pulses, when projected in vacuum, blow up drastically in less than 2 centimeters. The first part of this report describes the linear pinch apparatus and the ionized medium which it produces. The second part describes the effort to extract the relativistic electron beam from the X-ray machine and the results which were obtained when this was accomplished. (Author)
