NTF: Soldering Technology Development for Cryogenics [PDF]

, 1985
The advent of the National Transonic Facility (NTF) brought about a new application for an old joining method, soldering. Soldering for use at cryogenic temperatures requires that solders remain ductile and free from tin-pest (grey tin), have toughness ...

Magetoresistance of RuO_2-based resistance thermometers below 0.3 K

, 2001
We have determined the magnetoresistance of RuO_2-based resistors (Scientific Instruments RO-600) between 0.05 K and 0.3 K in magnetic fields up to 8 T. The magnetoresistance is negative around 0.5 T and then becomes positive at larger fields.

Analysis of Screwed Electrical Connections for HTS Tapes

Energies
A demountable connection is necessary to enable quick and easy replacement of high-temperature superconducting (HTS) tape samples during cryogenic (77 K) testing, particularly when investigating their application in superconducting fault current limiters

Heat loads and cryogenics for HE-LHC

, 2011
We report preliminary considerations on cryogenics for a higher-energy LHC ("HE-LHC") with about 16.5 TeV beam energy and 20-T dipole magnets. In particular we sketch the heat loads scaled on the proposed principal beam parameters and size the cryogenic ...

Electrodynamic sources of non-uniform heat production in composite superconductors causing instabilities [PDF]

, 1992
Model calculations of the electrodynamic properties of superconducting composites are usually carried out assuming that the material constants, such as critical current density and resistivity, are uniform over the cross-section of the composite, or at ...

Dc and ac behaviour of a normal joint in a superconducting cable [PDF]

, 1984
The application of joints which can be disassembled is studied within the framework of the development of high current (25 kA), high power (0.5 kW) cryogenic current supplies (flux pumps).1,2 The behaviour of a scale model with currents up to 5 kA will ...

A Novel Fuel-Based CO₂ Transcritical Cycle for Combined Cooling and Power Generation on Hypersonic Aircrafts

Energies
This study focuses on the great challenges for combined cooling and power supply on hypersonic aircrafts. To address the issues of low thermal efficiency and high fuel consumption of heat sink by the existing CO2 supercritical Brayton cycle, a novel fuel-
