Our group’s research is mainly instrumentation development for astrophysics and cosmology applications. In particular we are actively developing arrays of antenna‑coupled TES (transition edge sensors) detectors and instruments for the study of the polarization of cosmic microwave background radiation. CMB measurements provide compelling evidence for a period of exponential inflationary expansion in the early universe. Latest experimental evidences promise exciting opportunity that the polarization signal should be detectable with the next generation of instruments.

Rapid advances of detector technology played a decisive role in this experimental progression, from the discovery of the CMB to the exquisite temperature maps available today. Bolometers developed at JPL are poised to make defining measurements of the CMB for the next decade on the Planck satellite (launched in 2008). Moreover a new generation of antenna‑coupled bolometer arrays, a radical departure from the Planck ‘spider‑web’ design, is now ready to go beyond even the scientific capabilities of Planck, and will probe for the faint polarization signals produced by inflationary gravitational waves.

We are seeking an applicant to play a leading role in the development of the millimeter polarimeter with these JPL‑made large TES arrays. Experience in cryogenic systems and electrical and optical characterization of the TES arrays will be highly desirable. The candidate will integrate and optimize the recently built cryostat that was assembled with a pulse tube cooling system. The complete receiver will be fielded at the South Pole as one of the multiple receiver systems for the Keck experiment.
