MAGNETIC RECORDER FOR NUCLEAR PULSE APPLICATION. Covering Period: August 6, 1959 to October 5, 1959

Direct recording of nuclear pulse height data on magnetic tape is being investigated. The characteristics of various brands of commercial tape are being investigated and a waveform analysis is being performed in an attempt to determine the most favorable frequency range for available tapes. Use of the magnetic modulator head is being investigated to minimize variations due to short term tape speed variations. (W.L.H.)
