Abstract: A transient ionizing radiation tolerant peripheral system for a magnetic bubble memory includes a transient ionizing radiation tolerant rotating field coil driver and a transient ionizing radiation tolerant function gate controller. Both the transient ionizing radiation tolerant rotating field coil driver and the transient ionizing radiation tolerant function gate controller have predrivers each having a bipolar switching transistor having a base, a collector and an emitter. An anti-saturation diode is connected to the collector of the bipolar switching transistor to prevent its switching speed from being reduced by being driven into saturation by excess charge carriers generated by transient ionizing radiation. A photocurrent compensator is connected to the switching transistor and draws current away from its base during exposure to transient ionizing radiation.

Abstract: A panel system for exhibits comprises a plurality of upright rigid supporting members with generally planar members releasably connected on opposite sides to two adjacent supporting members. Each panel has an intermediate portion and along the two opposed edges are respective flange portions extending in opposite directions from said intermediate portion. This panel configuration enables the panels to be stacked in nesting fashion. Also provided are easily demountable header and lighting fixture subassemblies adapted to be affixed to the rigid members. Means are provided for detachably supporting horizontal rigid members upon the vertical rigid members and in other combinations as well.
