The Notre Dame QuarkNet Center (NDQC), a Research Community for Teachers, has extended an open-ended invitation to secondary school science teachers to participate in the activities of the high energy physics group from the Department of Physics at the University of Notre Dame. The NDQC is associated with the national QuarkNet program. Research at the center includes detector design and development for D0 at the Fermilab Tevatron, for CMS at CERN, and for the ILC.
