A Fermilab team has completed tests for a crucial superconducting segment for the PIP-II particle accelerator, the future heart of the Fermilab accelerator chain. The segment, called a cryomodule, will be one of many, but this is the first to be fully designed, assembled and tested at Fermilab. It represents a journey of technical challenges and opportunities for innovation in superconducting accelerator technology.

The U.S. Department of Energy has formally approved the scope, schedule and cost of the PIP-II project at Fermilab. The PIP-II accelerator will become the heart of Fermilab’s upgraded accelerator complex, delivering more powerful proton beams to the lab’s experiments and enabling deeper probes of the fundamental constituents of the universe.

The PIP-II Project, the first DOE particle accelerator project receiving substantial international in-kind contributions, held its first all-partner technical workshop from Dec. 1-4. The remote workshop included over 300 registered participants from seven countries spanning 11.5 time zones. The primary goal was to facilitate communication between the broader technical teams responsible for delivering hardware to PIP-II.

On Oct. 21, the PIP-II Injector Test Facility accelerated proton beam through its superconducting section for the first time. At this test bed for the upcoming PIP-II superconducting accelerator, collaborators will test novel particle accelerator physics concepts and technologies to be deployed in the high-tech front section of PIP-II, the future heart of the laboratory accelerator complex. The milestone achievement also marks the start of a new era at Fermilab of proton beam delivery using superconducting accelerators.
