Research Technican

Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions. We thrive on finding and cultivating talented people who are passionate about what they do. Join us and be a part of the diverse Caltech community. Job Summary The Research Technician will assist in experimental cosmology research in Prof. Bock's BICEP Array program. BICEP Array is leading the search for a polarized signal in the Cosmic Microwave Background from a primordial background of gravitational waves through mm-wave observations from the South Pole. The experiment relies on large arrays of bolometric detectors cooled to a low temperature of 100 mK. The Research Technician will assist in the micro-assembly of focal plane detector array wafers with superconducting SQUID readout chips and high-density wiring boards. The assembly requires making reliable electrical connections with wire bonds, followed by electrical continuity checks and debugging. The mechanical and electrical properties of the assembly will be documented to facilitate diagnosis during testing and operation. Duties may advance to cryogenic optical and electrical testing as the applicant accrues research experience. The applicant will work with graduate students, postdocs, and staff engaged in research in this program within a vibrant research environment. Essential Job Duties Micro-mechanical assembly of the focal plane components. Making electrical connections with wire bonds, electrically screening the arrays, measuring critical dimensions, and documenting the results in internal web postings. Screening component parts, which may involve cryogenic measurements of the superconducting SQUID readout chips. The Research Assistant may develop new assemblies for the TIME project. Other duties as assigned. Basic Qualifications Bachelor's degree in science, mathematics or engineering. Aptitude for experimental work in a laboratory setting, including careful hands-on assembly. Preferred Qualifications Prior experience with cryogenics, detectors, or low-noise electronics. Familiarity with mechanical and electrical design and associated software. Experience or background in CMB/millimeter-wave instrumentation. Required Documents CV. Cover Letter.
