First Silicon Modules for the PHENIX VTX
The nuclear group is helping to build a new detector (VTX) to upgrade the PHENIX experiment at RHIC. We recently passed a major milestone: the first silicon modules (sensor + readout electronics) came off the production line. Five done, over two-hundred to go! The current schedule is to install the VTX during summer 2010. The detector will enable us to separately measure charm and beauty production to help study the properties of the quark-gluon plasma.
