RADIATION HARDENING THE STANDING WAVE IMPEDANCE PROBE,
Abstract
The radiation hardening process for the Standing Wave Impedance Probe is discussed. Included in this process is the selection of radiation resistant components on the basis of a literature search, gamma radiation testing, and neutron radiation testing conducted by the Upper Air Research Laboratories. Indications were that many of the semiconductors, resistors, and insulators used in the original Impedance Probe were unreliable in a radiation environment such as encountered in the nuclear powered Agena satellite 626. This environment is expected to consist of a yearly radiation dose of 5 x 10 to the 12th power neutrons/cm square and 5 x 10 to the 7th power gamma rads. The choice of radiation resistant components based on the literature search findings was substantiated by a gamma radiation test at 7.5 x 10 to the 4th power rad/hr and a neutron radiation test supplying a total dose of 4 x 10 to the 13th power neutrons/cm square.
