Gary Koehler of the Engineering Division installs the multiple wire proportional chambers into the STAR Time Projection Chamber. This detector will play a key role in an upcoming effort to recreate and study what scientists believe was the dominant state of matter a few microseconds after the Big Bang. Later this year the detector will be shipped to Brookhaven National Laboratory, where it will become part of the STAR collider experiment aimed at studying quark-gluon plasmas.
