Students will be divided into 6 groups. Each group has ~9 students and will receive ~50 minutes hands-on training in the Main Control Room. The instructors are Bob Mau (Fermilab) and his colleagues. Students will have lunch at Fermilab and visit several sites, including the linac gallery, Wilson Hall, Industrial Buildings, CDF or D0, and the superconducting RF facilities.
