Description

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 are seeking one or more postdoctoral researchers with hands-on experience in low-temperature superconducting devices and far-IR to millimeter-wave instrumentation to join our team developing the world’s most sensitive far-infrared detectors. We are pursuing detector arrays in which each pixel provides background-limited performance in a dispersive spectrometer on a cryogenic space telescopes; that is a per-pixel noise equivalent power of 10^-19 W/sqrt(Hz) or lower. The researcher(s) will make use of a dilution-cooled sub-100mK cryostat to characterize devices built in the JPL micro devices lab (MDL). We are pursuing transition-edge-sensed (TES) bolometers, kinetic inductance detectors (KIDs), and quantum capacitance detectors (QCDs), with an initial emphasis on the bolometers in preparation for the SPICA mission. We will implement frequency-domain readout techniques developed by a range of US and international collaborators, and the candidate(s) should be willing to travel and interface with a diverse range of scientists and engineers in support of this activity. We envision that the thrust of the work will be in the low-NEP detector system demonstration, but opportunities also exist for collaboration on ongoing and proposed ground-based and balloon-borne instruments targeting the early Universe. Examples include SuperSpec (a millimeter-wave spectrometer on a chip slated for the large millimeter telescope targeting individual high-redshift galaxies ), TIME (a mm-wave tomographic intensity mapper targeting ionized carbon fro the Reionzation epoch), and TIM ((formerly STARFIRE), a proposed balloon-borne far-IR imaging spectrometer targeting the history of star formation when the Universe was half its current age). Key people in the JPL detector group include Pierre Echternach and Matt Kenyon
