Cryogenic Detectors: Physics, Fabrication, and Examples
| Abstract: |
Over the last 15 years, cryogenic detectors have become increasingly important for a wide class of applications. Much of this has been driven by the development of two types of cryogenic devices: transition-edge sensors and SQUID-based multiplexers. Instruments utilizing these two technologies have shown best-in-the-world energy resolution for x-ray, gamma-ray, and alpha particle spectrometers. These devices have also been used in many of the recently deployed long-wavelength astronomical cameras and polarimeters, where they have been used to make the first observations of both gravitational lensing and B-mode polarization of the cosmic microwave background. In this talk, I will discuss the physics and fabrication of these devices as well as describe examples of their application. |

| Speaker Bio: |
 Gene Hilton has been a senior staff scientist at the National Institute of Standards & Technology (NIST) in Boulder, Colorado for 18 years. He leads the fabrication effort of the Quantum Sensors Program, developing fabrication methods for superconducting sensors and multiplexing circuits. He and his team have delivered these components to more than 20 instruments deployed around the world. Prior to NIST, he spent six years at the General Electric Corporate Research & Development Center developing large-area, flat-panel x-ray detectors that are currently the market-leading technology for cardiac and mammographic imaging. He received his Ph.D. in condensed matter physics from the University of Illinois at Urbana-Champaign. |
