This one-year technology development effort will focus on the maturation of a variety of technologies related to a Topographic Imager (TI) investigation as envisioned for the NASA Europa Clipper mission concept. Our TI maturation and development work will be designed to reduce risks and to enable our investigation to play a critical a role in accomplishing the goals of all three Europa Clipper science objectives: (a) Ice Shell, (b) Composition, and (c) Geology. To satisfy the envisioned requirements for the TI in the radiation environment of the Europa Clipper mission, we will develop and test Sensor Chip Arrays (SCAs) comprised of Si-PIN detectors hybridized to radiation-tolerant Read-Out Integrated Circuits (ROICs). These devices are mature and have a digital output, which will minimize the electronics near the sensor and simplify the electrical interface. The SCAs, provided by Raytheon Vision Systems, will be tested at Ball Aerospace for functionality, and their performance will be thoroughly characterized before and after radiation exposure to levels appropriate for the stressing case of a long-life mission in the Jovian system. System-level trades for the instrument will also be performed to define the optimal format for the flight sensor and to advance the baseline instrument design.
