Short pulse transient radiation effects on a 92 K-bit magnetic bubble memory system

Short-pulse transient radiation experiments were performed on a commercial 92-K-bit magnetic bubble memory system. It is shown that when shielded or hardened electronics is used with the 92-K-bit magnetic bubble chip, data will be protected up to levels exceeding 10 to the 8th rads(Si)/sec during normal operations. For levels exceeding the upset thresholds of the support electronics, redundant unbiased magnetic bubble memory may be employed as spares in applications where multiple exposures of transient radiation are not probable.
