piDOSE-DCD/FM (Flight Model)

Space-Friendly™ Digital CubeSat Dosimeter.

Do you work in the area of Space Weather or wish to fly your own radiation measurement satellite constellation? Are you looking for a smart, miniature and low power space-grade radiation sensor? The piDOSE-DCD Industry's First Digital CubeSat Dosimeter (Geiger Counter) is the right unit for your needs. It is designed to provide the information about local gamma ray radiation background aboard small satellites in space, based on ten seconds and minute period measurements, without the use of high voltage geiger-tube sensors.

Latchup Kills. | Monitor Radiation.

Majority of small satellites use commercial (CMOS) electronics which are more and more sensitive to the radiation environment of space. Miniaturization is to blame. The less the size of the semiconductor technology, the less resistant to radiation, particle hit or energy deposition the system is. Bit flips in memories are the better outcomes of the radiation event or fly-through via South Atlantic Anomaly. A true latch-up can work as a crowbar circuit in your power system. Imagine tiny bondwires in semiconductor chips. If the current is too high, they can burn as fuse. Forever. The piDOSE can tell within 1 second that the environment is dangerous. Use the alarm to wake up - and turn off the power, before it is too late.

The PIN diode solid state radiation sensor is equipped with a scintillation crystal to extend the lateral sensitive volume to almost omnidirectional and wider energy range (~0.2 - 10 MeV).

The unit contains electrical outputs to signalize the Alarm threshold reached (similar to two times the ISS average dose rate), ERROR signal in case of sensor overload (overdose), INTERRUPT signal to signalize UART data packet transfer, Digital Counts Per Minute pulse output with equalized pulse width and Analog Counts Per Minute Output from the analog comparator.

There are six packets sent about counts per 10 second period, followed by a summary packet indicating doserate integrated over past 60 seconds added with telemetry information (voltage, temperature, uptime).

The 3.3V @ 30mW Ultra Low Power, low voltage solid state radiation detector replaces old, vintage, bulky, high-voltage Geiger-Müller tubes in a matchbox-sized form factor. The module provides data over the UART interface. The easy-to-parse format with ASCII lines are terminated with CR+LF and contains human-readable values.
