Cryogenic systems that use cryocoolers with conduction cooling for attaining temperatures
of 4.2 K and below routinely employ mechanically pressed components of copper to form the …

In recent years, theoretical and experimental interest in dark matter (DM) candidates have
shifted focus from primarily Weakly-Interacting Massive Particles (WIMPs) to an entire suite …

We present two different techniques for achieving low resistance (< 20 n Ω Ω) contacts
between copper and aluminium at cryogenic temperatures. The best method is based on …

For the transition to future electric flight high-power-density superconducting machines may
be an enabling technology. This also requires accurate thermal models to simulate …

This paper addresses technical problems of thermal contact conductance or resistance
which inevitably occurs in most cryogenic engineering systems. The main focus of this paper …

The detectors of the Super Cryogenic Dark Matter Search experiment at SNOLAB
(SuperCDMS SNOLAB) will operate in a seven-layered cryostat with thermal stages …

This dissertation describes advances in superconducting transition edge sensor (TES)
microcalorimeter technology for gamma-ray spectroscopy. Gamma-ray spectroscopy is used …

Cryostats that operate below 1 K have additional requirements involving the need for
extremely small heat leaks and alternative cooling methods. This chapter describes the …

This work was performed at the request of the Program Chief Engineer for Stratospheric
Observatory for Infrared Astronomy (SOFIA). The intended audience for this position paper is …

This study was conducted on the measurement of contact heat resistance existing between
blocks constituting the GMP equipment heating unit. The temperature distribution of molds …
