They sought to exploit the extensive infrastructure that had been built up at IUCF to make leading technical, as well as intellectual, contribu- tions to high-profile research projects at the major national laboratories for nuclear physics. The largest new project they undertook was to add an endcap electro- magnetic calorimeter to the STAR (solenoi- dal tracker at RHIC) detector at the new relativistic heavy-ion collider situated at Brookhaven National Laboratory. The main goal of the RHIC facility is to enable ultra- relativistic collisions of heavy nuclei, in which matter could be heated to tempera- tures previously attained only in the earliest instants following the Big Bang birth of the universe. At such high temperatures, it is anticipated that neutrons and protons will Steve Vigdor and Jim Sowinski stand beside the STAR endcap electromagnetic calorimeter “melt,” leaving a plasma of quarks and during its assembly on the STAR detector poletip at the relativistic heavy-ion collider in gluons, a state of matter never before September 2003.
