A system for detecting gamma radiation includes an array of radiation detection devices, each radiation detection device including a charge storage region in proximity to a high-z material; a set of decoders to address the radiation detection devices of the array of radiation detection devices and to provide signals indicative of a state of the radiation detection devices; a logic circuitry to determine the state of the radiation detection devices based on the signals the state of the radiation detection device; and a microcontroller in communication with the logic circuitry.

The present application provides a radiation sensor for deep space environments, comprising a circuit board; a payload control module, disposed on the circuit board; a radiation sensitive field-effect transistor readout module, also disposed on the circuit board and electrically connected to the payload control module; flash memory, disposed on the circuit board and electrically connected to both the payload control module and the radiation sensitive field-effect transistor readout module. The flash memory includes a detection software, which, upon detecting a single event upset in at least one bit of the stored sensor data, immediately identifies and records the position of the affected bit. The detection software then resets the data affected by the single event upset and records the number of bit errors.

Systems are provided for a controller of an X-ray detector. The controller includes a processor communicatively coupled to a distributed flash memory and configured to execute instructions for operation of the X-ray detector. The distributed flash memory includes a first flash memory which is physically distinct from a second (Nth) flash memory, wherein the first flash memory includes a loader including instructions to startup the X-ray detector.
