Preface

The 2019 Joint Cryogenic Engineering and International Cryogenic Materials Conferences were held from July 21 through July 25 at the Connecticut Convention Center in Hartford, Connecticut. As at past conferences, the international scope of these meetings was strongly maintained with 24 countries being represented by 613 attendees who gathered to enjoy the joint technical programs, industrial exhibits, and special events.

The program for the joint conferences included a total of 410 presentations in the plenary, oral, and poster sessions. Four plenary talks gave interesting in-depth overviews and discussions on the topics of the growing field of commercial application of hydrogen fuel-cells for specialized applications and large-scale semi-truck transportation, and recent 5x increase of liquid hydrogen production in the U.S.; Siemens' perspectives on evolving hybrid-electric propulsion technologies for large commercial aircraft; the world-leading research opportunities with rare isotopes in nuclear physics, nuclear chemistry, and the application of rare isotopes for society that the Facility for Rare Isotope Beams (FIRB) at Michigan State University will soon provide; and the impressive progress designing the nextgen SPARC fusion reactor 1^st-ever utilizing 2^nd-generation high-temperature-superconducting (HTS) wire. The attendees also convened for two Special Joint CEC-ICMC Symposia on i) Transportation, and ii) Quantum Computing, and seven Special-or-Focus Sessions were included in the programming emphasizing high-quality invited talks. Contributed papers covered a wide range of topics including many aspects in advances in cryogenics and superconductors, along with their applications. Both CEC and ICMC boards are encouraging student participation and career growth and provided registration support for 36 student applicants. In total, 207 papers were submitted for publication of which 190 are published in these conference proceedings.
