The National Bureau of Standards Boulder Laboratories at Boulder, Colorado once again served as the host for the 1972 Cryogenic Engineering Conference.

Support from the National Science Foundation has made it possible for the tenth annual Cryogenic Engineering Conference, hosted by the University of Pennsylvania and capably directed by K.

The University of Colorado and the National Bureau of Standards have once again served as hosts for the Cryogenic Engineering Conference in Boulder, Colorado.

These sessions were divided into the following general topics: Cryogenic Processes Cryogenic Equipment Cryogenic Properties Cryogenic Applications Bubble Chambers The division in some cases had to be somewhat arbitrary since several papers could have been classified under more than one general topic.

Cryogenic engineering is concerned with developing and improving low temperature processes, techniques, and equipment; It is rather difficult to assign a definite temperature which serves to divide refrigerating engineering from cryogenic engineering.

The 1965 Cryogenic Engineering Conference, in presenting the papers of its eleventh annual meeting takes this opportunity to gratefuIly acknowledge the assistance of Rice University and, in particular, R. The highlight of this conference has been the presentation of the highest Cryogenic Engineering Conference award-The Samuel C.

The 1959 Cryogenic Engineering Conference Committee is pleased to pre sent the papers of the 1959 Cryogenic Engineering Conference. vii ACKNOWLEDGMENT The Cryogenic Engineering Conference Committee is deeply grateful for the continued support and interest of the following organizations who made the 1959 Cryogenic Engineering Conference possible.

The 1960 Cryogenic Engineering Conference Committee is pleased to present the papers of the 1960 Cryogenic Engineering Conference.

1969 marked the return of the Cryogenic Engineering Conference, now affiliated with the National Academy ofSciences through the Division ofEngineering, National Research Council, to the University of California at Los Angeles.

1970 marked the seventh return of the Cryogenic Engineering Conference, now affiliated with the National Academy of Sciences through the Division of Engineering, National Research Council, to Boulder, Colorado.

Even though no Cryogenic Engineering Conference was held in 1971, it became quite evident to the Conference Board that there were sufficient advances in cryogenic engineering to warrant the publication of Volume 17 of the Advances in Cryogenic Engineering.
