International Workshop on Cryogenic Structural Materials and their Evaluation Methods, 2013

July 16, 2013 (HE77).  The Special Workshop on Cryogenic Structural Materials and their Evaluation Methods was held at Fairbanks, Alaska, US, on June 15-16, 2013.  It was a pre-conference event of CEC/ICMC 2013, organized to celebrate the retirement of Prof. T. Ogata of the National Institute for Materials Science (NIMS) in Japan, which is scheduled for March 2014.  Prof. T. Ogata has been working on the cryogenic materials and methods of evaluating their mechanical properties for more than 30 years.

The workshop included several interesting invited presentations on cryogenic structural materials and their evaluation methods. Several of these invited talks were about ITER magnet-related materials.
