Title: SSVD Extreme Temperature Electronics for Planned Venus Missions
Agency: NASA
Contract: NNG04CA86C
Award Amount: $70,000.00


The purpose of this project is to demonstrate, based on a new class of electronic devices called solid state vacuum devices (SSVD?s), a highly promising enabling technology for extreme high temperature radiation hard electronics. SSVD?s marry solid state semiconductor technology, including the process fabrication techniques, with vacuum electronics, and, in this case, specifically thermionic vacuum electronics. SSVD?s have already been demonstrated for highly demanding high frequency applications. Thermionic SSVD?s, in which vacuum transport is by thermionically emitted electrons, are especially promising due to their intrinsic internal high temperature operation and radiation hardness. SSVD?s should be extremely well suited for extreme environments that, for example, exist on or near Venus. Currently no existing electronics can address this extreme environment. InnoSys proposes to demonstrate thermionic SSVD? triodes/field effect transistors and the associated assembly and sealing to meet the requirements needed for extreme high temperature electronics. In particular, to demonstrate this capability, 460oC electronics for low noise (less than 10 nanovolt/square root(Hz)) and 0 to 100 volt or higher output circuitry and appropriate innovative temperature and pressure assemblies and sealing techniques needed for reliable and sustained operation of SSVD? devices for NASA robotic, sensor and actuators applications will be studied.
