uDOS001
Overview
The 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.
- Enables routine monitoring of spacecraft radiation environment
- Custom microchip in a small footprint package which results in significantly lower weight and power than alternative devices
- Can be mounted in multiple locations on spacecraft
- Correlates environmental models and ray-tracing analyses with real in-flight measurements
- Provides total mission dose to aid in diagnosis of spacecraft anomalies that result from changes in environmental fluxes
- Dosimeters can be integrated to standard spacecraft housekeeping systems
- Measures up to 40 krad(Si)
- Mechanical dimensions: 1.4” x 1.0” x 0.040”
- 20 grams in weight
- 10 mA from 13 Vdc to 40 Vdc input
