Pb-glass Detectors for FPD Upgrade to STAR

There are two types of calorimeters that are being prepared.  Calorimeters that will be mounted left and right of the beam pipe on the east and west sides of STAR will consist of three components:

A test stacking of the Pb-glass detectors is shown in the picture below.  In front of the Pb-glass stack are SMD planes with wave-length shifting optical fibers that will collect the scintillation light and transport it to individual pixels of a multi-anode photomultiplier tube.
