The 1987 joint Cryogenic Engineering Conference/International Cryogenic Materials Conference was held at the Pheasant Run Resort, St. Charles, lliinois from June 14 to 18. Fermi National Accelerator Laboratory, located a few kilometers from Pheasant Run, was the host for this conference. There is a great deal of cryogenic research and development underway at Fermilab and many applications of cryogenic materials and systems are in rou­ tine, daily use at the Tevatron. The technical program for the joint conference had over 300 invited and contributed papers from many different countries. The CEC board and I have tried to dramatically shorten the publication time of this volume of Advances in Cryogenic Engineering. In order to help meet the goal of the February publication, I asked the reviewers to complete their reviews before leaving Pheasant Run, after the conference. I would like to thank all of the reviewers for their prompt and throughtful reviews. I very much appreciate the authors following the prescribed format and responding quickly to my requests for revisions.
