The Hardening of Satellite Cables to X-Rays
Abstract
Several classes of satellite cables are irradiated in SPIRE corporation's SPI-PULSE 6000 X-Ray facility in order to identify hardening techniques for cables, and to verify computer models of the X-Ray induced response of cables (MCCABE code). The following techniques for hardening cables are shown to be effective: (1) filling the voids between conductors and insulation; (2) employing coaxial cables rather than cable bundles; (3) reducing the atomic numbers of the conductor materials; (4) using conductive plastic coatings between conductors and insulation. The following techniques for hardening cables was found to be ineffective: matching atomic numbers between conductors and insulation. Model results generally agreed in sign with experiment. The predicted magnitude of response ranged from an order-of- magnitude too low, to essential agreement within experimental error, depending on how well the voids between conductors and insulation were defined.
