Radiation Hardness of a New Magnetic Thin-Film Recording System

Magnetic thin-film memory units of a new transient-recording system designed for nuclear data acquisition were tested for radiation hardness. The films were exposed to neutron and gamma doses on the order of 1012 n/cm2 and 104 R, respectively. Analog signals stored in the films were photographed using a Suchow powder technique before and after the exposure.
