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.
