This paper describes progress towards the development of a large‐capacity, single‐stage,
Stirling‐type, pulse‐tube refrigerator (PTR) for high temperature superconducting power …

A hybrid pulse-tube/reverse-Brayton cryocooler is being developed that integrates a
regenerative, pulse-tube upper stage with a recuperative, reverse-Brayton lower stage using …

Distributed loads are frequently encountered in large deployable structures used in space
applications such as optical mirrors, actively cooled sunshades, and on focal plane …

A first‐order model is developed for a pulse tube refrigerator including the primary
components and important parameters affecting the energy and exergy transport in the …

Future space‐based systems will require long‐life, active cryocoolers capable of achieving
sub‐10 K load temperatures. Currently, the available cryocooler technology at these …

This paper describes the design and preliminary experimental results for a large capacity
(300W at 65 K) single-stage, Stirling-type pulse-tube. The regenerator, the critical …

In future space applications, widely distributed sensors, as well as, large deployable
structures, such as mirrors and sunshades, will require active thermal control. However …

ABSTRACT A loss parameter is introduced into the first order thermodynamic model of a
pulse tube consisting of a hot, a cold and an adiabatic section to quantify the pulse tube …
