Superconducting Transition Edge Sensor for Gamma-Ray Spectroscopy

Superconducting Transition Edge Sensor for Gamma-Ray Spectroscopy

Superconducting Transition edge sensor (TES) coupled with a heavy metal absorber is a promising microcalorimeter for Gammaray (γ-ray) spectroscopy with ultra-high energy resolution and high detection efficiency. It is very useful for the non-destructed inspection of the nuclide materials. High resolving power of γ-ray peaks can precisely identify multiple nuclides such as Plutonium (Pu) and Act...

Superconducting Transition Edge Sensor Bolometer Arrays for Submillimeter Astronomy

Studies of astrophysical emission in the far-infrared and submillimeter will increasingly require large arrays of detectors containing hundreds to thousands of elements. The last few years have seen the increasing from one to a few tens of bolometers on ground-based telescopes. A further jump of this magnitude, to a thousand bolometers, requires a fundamental redesign of the technology of makin...

The Superconducting Transition Edge Sensor (TES) Microcalorimeter Innovation Pathway

Gestation (pre-1996) In a sense, all of the previous decade of semiconductor microcalorimeter development played an important role in the gestation of the TES microcalorimeters. By the mid 1990s, the Goddard calorimeter group had emerged as a recognized leader in the field, and as a result, had continued to attract top talent from, and established strong connections with, most of the leading in...

Instrumentation for Gamma-Ray Spectroscopy

The subject of ttis chapter is the function and operation of the components of a gamma-ray spectroscopy system. In Chapter 3 it was shown that the output pulse amplitude from most gamma-ray detectors is proportional to the energy deposited by the gamma ray. The pulse-height spectrum from such a detector contains a series of full-energy peaks superimposed on a continuous Compton background. Alth...
