DOE/Fermi National Accelerator Laboratory Building something as complex as a superconducting cryomodule takes the efforts of an entire team of scientists, engineers and technicians.

Sometimes that thing is a highly complex machine designed to accelerate an 800-million-electronvolt proton beam to enable decades' worth of cutting-edge experiments at the United States' foremost particle physics laboratory. In January, scientists and engineers at the Department of Energy's Fermilab successfully completed phase-one testing on a prototype of the first superconducting cryomodule to be fully designed, assembled and tested at Fermilab for the PIP-II accelerator.
