Modern Techniques for Neutron and Gamma-ray Spectrometry and Imaging

Description

The Energetic Particle Lab (EPL) in the Heliophysics Science Division is currently building instruments to measure charged and neutral particles. Instrumentation is based on solid state detectors and modern scintillators readout with silicon photomultipliers (SiPM). Opportunities exist to establish a research area modernizing neutron and gamma-ray spectrometers. These instruments are vital for Heliophysics, Planetary, and Astrophysics and often are highly interdisciplinary. There are also commercial opportunities for such spectrometers with a high potential for technology transfer. A particular emphasis is on developing spectrometers for the Artemis program both to conduct trailblazing science while safeguarding astronauts against radiation exposure during deep space travel and lunar surface expeditions. The current emphasis is to reduce the power, mass, and volume of well-established neutron/gamma-ray instrumentation and to expand the readout to more robust systems including rad-hard SiPMs and novel multi-channel ASICs. We are also exploring modern scintillators and solid-state options for detecting neutrons from thermal, to epi-thermal, to fast neutrons -- covering the entire range of neutron energies. We are also interested in simulating the response and environment that is applicable for such instrumentation.

About the NASA Postdoctoral Program

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
