Special Session “Lesson Learned”
(sponsored by Institute for Materials Research, Tohoku University)
Special session “Lesson learned” is organized in the evening (JST) on Nov. 17. It is quite important to share the knowledge obtained in a history of superconducting devises such as accelerator, fusion, NMR/MRI, high field magnet and so on. Most improvements and achievements can be found in the literatures. On the other hand, lessons based on the operation and the troubles are not so accessible in spite of those importance. This session focuses on those quite important lessons learned in HTS and LTS devices. Six experts from fusion, accelerator, high field magnet communities are invited. The session organizer is Prof. Pierluigi Bruzzone, PSI, Switzerland.
