Superfluid

John Weisend is currently a Senior Accelerator Engineer at The European Spallation Source and an Adjunct Professor at Lund University. He received his Ph.D. in Nuclear Engineering & Engineering Physics from the University of Wisconsin – Madison, where he investigated engineering applications of He II. He has worked at the SSC Laboratory, the Centre D’Etudes Nucleaires Grenoble, the Deutsches Elecktronen-Synchrotron Laboratory (DESY), the Stanford Linear Accelerator Laboratory (SLAC), the National Science Foundation and Michigan State University. Dr. Weisend’s research interests include He II and large scale accelerator cryogenics. He is the Chairman of the Board of Directors of the Cryogenic Society of America (CSA). He has led the CSA Short Course Program since 2001. He is Chief Technical Editor of Advances in Cryogenic Engineering and Section Editor in Chief for the European Physical Journal Techniques and Instrumentation. In addition to co-authoring more than 60 technical papers, Dr. Weisend he has co-authored or edited several books, most recently (with G. Terence Meaden) a biography of Kurt Mendelssohn, Going for Cold (2021). He was made a fellow of the Cryogenic Society of America in 2021.

“Weisend goes well beyond the physics, and provides a clear and concise description of how superfluid helium is used by engineers in scientific experiments. The book is illustrated using original technical drawings, which gives it a warm and historical feel.” (Hamish Johnston, physicsworld.com, February 14, 2024)
