NIU engineering students (from left) Stefan Nyholm, Svilen Batchkarov and Caeden Keith explain their senior design project to their professor, Tariq Shamim (front, back turned) at Fermilab’s CMTF. The team built a full-scale mockup of PIP-II’s HB650 cryomodule that will be used for fit checking and preparing test stand and accelerator locations for the real cryomodule.
