We present the development of a two-stage PrNi$$_5$$5 continuous demagnetization refrigerator at the Institut Nel/CNRS and numerical simulations of its performance. The thermal model used in the simulations is discussed in detail including the likely sources of heating. We demonstrate the effects of the critical thermal links including superconducting heat switches as well as the heat conductivity of the PrNi$$_5$$5, accounting for the dependence of cooling power on the PrNi$$_5$$5 rod diameter… Expand

Cryogenic broadband vibration measurement on a cryogen-free dilution refrigerator
Abstract This manuscript reports a set of acceleration measurements in the frequency range from 0 to 50 kHz performed at the mixing chamber plate (2 axes) and the top flange (3 axes) of aExpand
Very Low Resistance Al/Cu Joints for Use at Cryogenic Temperatures
We present two different techniques for achieving low resistance ($<$20 n$\rm \Omega$) contacts between copper and aluminium at cryogenic temperatures. The best method is based on gold plating of theExpand
Design evaluation of serial and parallel sub-mK continuous nuclear demagnetization refrigerators

Optimization procedure for the cooling of liquid 3He by adiabatic demagnetization of praseodymium nickel
The construction and performance of a single stage nuclear demagnetization apparatus utilizing 0.267 mole of praseodymium nickel material is described. An optimization procedure to minimize entropyExpand
Nuclear refrigeration properties of PrNi5
Properties of the metallic Van Vleck paramagnet PrNi5 which are relevant for its use as a nuclear refrigerant (particularly its nuclear entropy) have been measured, and are discussed in comparison toExpand
Superconducting aluminum heat switch and plated press-contacts for use at ultralow temperatures.
Al is a better material for a heat switch than the usually used superconductors because of its large k(n) and large Debye temperature (reducing the lattice conductivity k(s). Expand

Constellation-X is a multi-satellite X-ray astronomy mission presently being planned for launch in the 2010 time frame. Each of four identical satellites will contain a telescope and instruments forExpand
Electrical Conductance of Bolted Copper Joints for Cryogenic Applications
We present the results of electric contact resistance measurements at low temperatures on copper-to-copper bolted joints. Our accurate and systematic data display a rather small dispersion, and mayExpand
The thermal conductivity of PrNi5; electroplating of PrNi5
Abstract Thermal conductivity measurements on two rod-shaped samples of PrNi5 are presented. Their RRR values were 2.34 and 15, respectively, whereas their conductivities can be described by κ = 0.12Expand
