ORAU is Hiring an Advanced THz HEB mixers for Astrophysics Near Greenbelt, MD
OrganizationNational Aeronautics and Space Administration (NASA)
Reference Code0293-NPP-NOV24-JPL-TechDev
How To ApplyAll applications must be submitted in Zintellect
Please visit the NASA Postdoctoral Program website for application instructions and requirements: How to Apply | NASA Postdoctoral Program (orau.org)
A complete application to the NASA Postdoctoral Program includes:
DescriptionAbout the NASA Postdoctoral ProgramThe NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented U.S. and non-U.S. 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:This research opportunity focuses on the development of the broadband THz Hot-Electron Bolometer (HEB) mixers with the ultimate sensitivity for operation on orbital and suborbital platforms. Such mixers will be important for the advancement of astrophysical heterodyne receivers. The main application of these detectors would be in the THz line spectroscopy of the interstellar molecular clouds and THz interferometry in space. Both NbN and MgB2 based HEBs are of interest. The new topic of the research in the device physics is an exploration of the negative electro-thermal feedback mechanism for mixing. The Integration of the mixers with Quantum Cascade Laser (QCL) local oscillators (LO) is of particular interest. Also important are technologies allowing the integration of the HEB mixers into arrays. The activities include laboratory investigations and optimization of the mixer devices (conversion gain, IF bandwidth, noise temperature, LO power, THz coupling, etc.) and also development and construction of prototype receivers (single-pixel and multi-pixel) based on mechanical cryocoolers. The previous experience with THz mixers, TES detectors, THz receivers & measurements, and corresponding laboratory techniques is required. Microwave experience is a big plus. Microfabrication experience is desirable.
