โฆ Synopsis
attracted an exceptional attendance with over 300 contributed papers indicating a growing interest in cryogenic applications and materials. CEC Chairman, Dr T. Flynn opened the meeting with a dedication to Dr K. Timmerhaus for his 25 years of continuous and unrelenting service as editor of Advances in Cryogenics. Dr R. Fast will take up the editor's tasks to continue in the high quality tradition established.
ICMC Chairman Dr W. Morris introduced the first of several outstanding plenary speakers, Dr S. Dean of Fusion Power Associates. Dr Dean discussed the prospects for fusion power as one of the candidates for providing the bulk of the world's long term energy needs. Several examples of cryogenic applications to fusion energy were cited such as large superconducting magnets, cryopumping and materials.
