Simulation of Electron and Ion Lenses for Mass Spectroscopy

Princeton Electronic Systems (PES), proposes to utilize the world's most advanced 3-dimensional charged particle trajectory simulation software available with Sarnoff to provide NASA with accurate performance simulations of mass spectrometers used for detection and measurement of planetary atmospheric constituents. PES proposes a 3-phase program. Phase 1, a 6-month effort, will demonstrate the capability of the software for mass spectrometric applications. The software was developed over 30 years and with an investment of 50 million dollars, to provide highly accurate and comprehensive analyses of performance of electron and ion lenses. Phase 2 effort will validate the accuracy of the proprietary software by modeling the detailed geometry and performance of a particular spectrometer lens design and experimentally measuring the performance. Phase 2 will also lay the groundwork enabling NASA and its contractors to submit requests for simulations and designs to be performed in the future. In Phase 3, the software will be used in the design, prototype fabrication, and manufacture of highly-portable and compact, i.e. hand held mass spectrometers, which as commercial- off-the-shelf products would be capable of revolutionizing and expanding the current $500 million dollar commercial marketplace and application areas for mass spectrometers. Benefits that NASA will achieve include: improved sensitivity, light-weight spectrometers for space payloads, enhanced recognition for efforts with industry to develop and commercialize new products.
