Highly miniaturized ASIC radiation detector, MIDAS (ESA)

The MIDAS device is developed in response to the European Space Agency requirement for a device whose size, power consumption and radiation data output will increase the level of space-flight crew autonomy as far as it concerns operational decisions related to radiation hazards. It has been designed as a wristwatch dimensions cube detector for measuring track direction and energy deposition in silicon pixels, as well as energy depositions by neutrons in a plastic scintillator which is the core of the cube. Miniaturization is achieved by using fully depleted silicon pixel detectors with the signal processing electronics residing on pixel.
