Shielding of specific electronic components from the harsh bremsstrahlung environment expected on PBFA II has been investigated. 3-D Monte Carlo estimates of dose in locations throughout the facility have been compared with electronic technology thresholds to identify possible problem locations or technologies. In some parts of the facility, implementation of the 30-MV lithium ion diode option will increase dose rates to electronic equipment above tolerable levels. As a result, additional close-in shielding is being employed and some components are being moved to lower radiation level locations. None of the changes are prohibitive in terms of time, cost, or accelerator utility.
