Development of superconducting far-Infrared photon counting detector arrays
New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission—your opportunity—is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL.
Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.
The selected candidate will work on developing the Quantum Capacitance Detector, a far-Infrared detector based on mesoscopic superconducting devices. The candidate will work on some, but not necessarily all of the aspects of the development such as: 1. Electromagnetic design of pixel architecture and arrays using software such as Sonnet or equivalent 2. Layout of design for photomask fabrication 3. Mechanical design of focal place arrays 4. Fabrication of devices in a clean room environment 5. Optical characterization of devices in a low-background dilution-cooled test facility. 6. Development of RF-multiplexed readout of large (at least 500 pixel) arrays operating with readout frequencies between 300MHz and 3 GHz. The postdoc will work alongside Drs. Pierre Echternach and Matt Bradford (co-advisor). The appointee will carry out research in collaboration with the JPL advisors, resulting in publications in the open literature.
Candidates should have a recent PhD in Physics, Applied Physics, Electrical Engineering, or Astronomical Instrumentation. Experience in developing superconducting devices and/or low-noise far-infrared/submm direct detectors. Experience with sub-Kelvin cryogenics, electromagnetic design software such as Sonnet, HFSS or equivalent. Experience with RF frequency-domain multiplexing techniques is a plus. Candidates who have received their PhD within the past five years since the date of their application are eligible. Postdoctoral Scholar positions are awarded for a minimum of one-year period and may be renewed up to a maximum duration of three years.
Candidates should submit the following to this site: CV, representative publications, contact information for three references, and a cover letter stating their research accomplishments and interests.
