“…To verify our results we simulated the performance of an existing microcalorimeter and compared the results with data from the detector. We considered a microcalorimeter used in the development phase of the X-Ray Spectrometer (XRS) for the Astro-E satellite [18]. The detector that we used for the comparison was part of a 6x6 test array of microcalorimeters with silicon implanted thermistors and HgTe absorbers.…”

The standard non-equilibrium theory of noise in ideal bolometers and microcalorimeters fails to predict the performance of real devices due to additional effects that become important at low temperature. In this paper we extend the theory to include the most important of these effects, and find that the performance of microcalorimeters operating at 60 mK can be quantitatively predicted. We give a simple method for doing the necessary calculations, borrowing the block diagram formalism from electronic control theory.

We discuss a new type of direct detector, a silicon hot-electron bolometer, for measurements in the far-infrared and submillimeter spectral ranges. High performance bolometers can be made using the electron-phonon conductance in heavily doped silicon to provide thermal isolation from the cryogenic bath. Noise performance is expected to be near thermodynamic limits, allowing background limited performance for many far infrared and submillimeter photometric and spectroscopic applications. We report measurements of device I-V characteristics and terahertz surface impedance.

“…Work with low-α thermistor-based calorimeters, where heat capacity constraints rule out all absorbers except superconductors and insulators, has shown that high-purity Sn and HgTe absorbers provide good energy resolution [119,120]. Recent work [97] on TES gamma-ray calorimeters also use glued tin absorbers.…”

In recent years, superconducting transition-edge sensors (TES) have emerged as powerful, energyresolving detectors of single photons from the near infrared through gamma rays and sensitive detectors of photon fluxes out to millimeter wavelengths. The TES is a thermal sensor that measures an energy deposition by the increase of resistance of a superconducting film biased within the superconducting-tonormal transition. Small arrays of TES sensors have been demonstrated, and kilopixel arrays are under development. In this chapter, we describe the theory of the superconducting phase transition, derive the TES calorimeter response and noise theory, discuss the state of understanding of excess noise, and describe practical implementation issues including materials choice, pixel design, array fabrication, and cryogenic SQUID multiplexing.
