ICMC-14 - Cryogenic Materials Testing and Methods
Invited Oral Presentation
Mechanical testing of materials at low temperatures is one of the cornerstones of the Mechanical and Material’s Engineering (MME) group at CERN. A long tradition of more than 20 years and a unique know - how of such tests has been developed with a 18 kN double-walled cryostat. Large campaigns of material qualification have been carried out and the mechanical behavior of materials at 4 K has...

ICMC-12 - Insulation and Impregnation Materials
Contributed Oral Presentation
The thermal contraction from room temperature to 4 K of electrical insulation materials has been measured using a modified Invar 36 rod-in-tube dilatometer.The test assembly permitted independent measurement, simultaneously, of two samples. This permitted the use of a reference and an insulation sample for each thermal run. Materials that were measured included a conventional epoxy resin,...

ICMC-14 - Cryogenic Materials Testing and Methods
Contributed Oral Presentation
An apparatus and method for the low-temperature mechanical training of shape memory alloys has been developed. The shape memory alloy (SMA) materials are prototypes being developed for novel thermal management systems in future cryogenic applications. Alloys providing two-way actuation at cryogenic temperatures are the chief target. The mechanical training regime was focused on the controlled...

ICMC-12 - Insulation and Impregnation Materials
Contributed Oral Presentation
The development of new generation superconducting magnets for fusion research, such as the ITER experiment, is largely based on coils wound with so-called ‘cable-in-conduit’ conductors. These cable-in-conduit conductors consist of various types of stainless steel jackets, densely filled with superconducting strands based on either Nb3Sn or NbTi, and subsequently compacted. The concept of the...

ICMC-14 - Cryogenic Materials Testing and Methods
Contributed Oral Presentation
Liquid propellant tank insulation for space flight requires low weight as well as high insulation factors. Use of Spray-On Foam Insulation (SOFI) is an accepted, cost effective technique for insulating a single wall cryogenic propellant tank and has been used extensively throughout the aerospace industry. Determining the bond integrity and the SOFI’s ability to withstand the strains, both...
