Abstract:

Several classes of satellite cables are irradiated in SPIRE corporations 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.
