Colloquium: Focal Plane Technology for Observational Cosmology

January 29

4:00pm - 5:00pm

Speaker: Gene Hilton, PhD; National Institute of Standards and Technology (NIST)

Abstract: In the last two decades, satellite measurements of the anisotropy of the cosmic microwave background (CMB) have transformed our understanding of the early universe. These results have prompted the development of new ground- and balloon-based instruments for measurement of the polarization of CMB. The key technology underpinning these instruments is superconducting microelectronics for the detectors and readout of these polarimeters. 

This talk will motivate and describe the requirements on these instruments and discuss the operation and fabrication of the superconducting detectors and readout circuits for this application.

Hosted by DU's Department of Physics and Astronomy.

4:00 p.m. in Olin Hall 105
