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.

Description:

We have pioneered the development of cryogenic microcalorimeters for high resolution, non-dispersive x-ray spectroscopy. An array in the current generation of microcalorimeters typically has 36 pixels with better than 6-eV resolution and we are now working in several directions to fabricate arrays with many more pixels (100-1000) and with higher spectral resolution (2 eV). Some of the specific technologies we are pursuing use doped silicon, superconducting transition edge sensors, and magnetic calorimeters. We are also expanding the capability of these devices by optimizing pixel design for specific energy ranges (i.e., soft and hard x-rays). We have several cryogenic facilities that can reach 50 mK for this work and access to state-of-the-art processing facilities for device fabrication. This technology is being developed principally for space applications, but we are also using this to support a vigorous program in laboratory astrophysics using an electron beam ion trap to simulate astrophysical plasmas. This work provides some of the atomic physics data needed for modelling celestial spectra and also valuable operational and calibration experience with these very sensitive spectrometers.
