Shown here is the central portion of the Heavy Flavor Tracker (HFT) being installed at the Relativistic Heavy Ion Collider's STAR detector. The HFT will track particles made of "charm" and "beauty" quarks, rare varieties or flavors that are more massive than the lighter "up" and "down" quarks that make up ordinary matter. The Solenoidal Tracker at RHIC (STAR) is a detector which specializes in tracking the thousands of particles produced by each ion collision at RHIC. Weighing 1,200 tons and as large as a house, STAR is a massive detector. It is used to search for signatures of the form of matter that RHIC was designed to create: the quark-gluon plasma. It is also used to investigate the behavior of matter at high energy densities by making measurements over a large area.
