Résumé

Compression tests have been performed on solid neon to determine Young's modulus and compressive strengths in the temperature range from 8 to 23 K. This data was used for structural analysis of the X-ray Spectrometer's (XRS) solid neon dewar. The dewar is nearly full of a 2.5% dense aluminium foam, so measurements were made for samples where solid neon was formed within the aluminium matrix as well as pure solid neon samples. As a further check and to verify the structural model, thermal cycle tests were conducted on a small scale toroidal dewar filled with solid neon. Mechanical properties measurements and data are described, along with model predictions and actual performance of both the engineering unit XRS dewar and the sub-scale dewar.
