Teledyne Advanced Electronic Solutions Micro Dosimeter (P/N UDOS001) is a compact hybrid microcircuit which directly measures total ionizing dose (TID) absorbed by an internal silicon test mass. The test mass simulates silicon die of integrated circuits on-board a host spacecraft in critical mission payloads and subsystems. By accurately measuring the energy absorbed from electrons, protons, and gamma rays, an estimate of the dose absorbed by other electronic devices on the same vehicle can be made. The Micro Dosimeter can operate from a wide range of input voltages. The accumulated dose is presented to three DC linear outputs and one pseudo-logarithmic output giving a dose resolution of 14 uRads and a measurement range up to 40 kRads. These outputs are intended to be directly connected to most analog-to-digital converters (ADCs) or spacecraft housekeeping analog inputs (0-5V range), which makes minimal demands on the host vehicle. The Micro Dosimeter incorporates a test function to allow electrical testing of the hybrid without the need for a radiation source.

 

  • Integrates signal prior to threshold detection to improve charge collection accuracy
  • 3 linear DC and 1 pseudo-log output pins
  • Dose budgets can be developed to establish more accurate estimates of spacecraft life
  • 2 U.S. Patents
  • Teledyne requests that the Micro Dosimeter data be made available to The Aerospace Corporation for the purpose of improving space environment models used to predict radiation dose with the multitude of Micro Dosimeter data obtained from orbits.
