Fast Nuclear Event Detection and Circumvention System FPA ROIC

Since modern microelectronics are capable of responding in times comparable to gamma pulse risetimes, it is critical to have circumvention techniques that offer protection in the same time frames. We will couple Nu-Trek's ultra fast GaAs detector technology (< 30 ps response time) with Titan/Jaycor's System Hardening Upset Recovery (SHUR) technology for a sub-nanosecond nuclear event detector and circumvention system, UF-SHUR (adjustable and staged engagement, E6-E10 rad(Si)/s). SHUR is a macro cell library sponsored by DTRA available to all government contractors for use in their designs. UF-SHUR is especially applicable to COTS devices and systems, as it enhances radiation hardness on a system level. UF-SHUR will protect the sequencer control electronics to the FPA, the calibration data memory, all the interfaces between the analog signal processor and the digital signal processor. Additional features include false-write protection, prompt immune signal pass-through, hardened clock generation circuitry, multiple fault masking, off-line timer, and hardened recall registers. In addition, an Ultra Fast Nuclear Event Detector will be spun off as a commercial product.
