Abstract
The Tiny Remote-sensing Instrument for Thermospheric Oxygen and Nitrogen (TRITON) is being developed by the U.S. Naval Research Laboratory (NRL) for detection of neutral components of the daytime thermosphere. TRITON measures naturally occurring, far ultraviolet (FUV) emissions of the upper atmosphere that are produced as a result of solar excitation. The sensor concept is based primarily on multiple sensors previously developed at NRL with recent spaceflight heritage. The legacy optics have been under evaluation and development for extension to new emission targets and brighter ambient environments. Recent TRITON development work has included characterization of a new photomultiplier tube and comparison to performance of a previously used model. In addition, several bandpass filters are evaluated for their effectiveness in providing the out-of-band rejection needed to isolate the FUV and MUV emissions of interest. The primary optical layout of TRITON sensors will be described to highlight the components that have been changed or adapted for use in the new configuration. The results of recent lab tests will also be shown to demonstrate the expected performance of TRITON relative to prior, legacy components and subsystems.
