STAR Forward Pi0 Detector (FPD)
The FPD was mounted on the east tunnel platform extension,
~750 cm from the STAR interaction point for the FY01/02 run. Its
purpose is to measure energetic photons produced in collisions at the STAR
interaction point. For that run, two different technologies were
the north calorimeter (Yellow beam left) was a lead-scintillator
sampling calorimeter capable of measuring longitudinal and transverse profiles
of electromagnetic showers.
the south calorimeter (Yellow beam right) was a 4×4
array of 1.5" × 1.5" × 18" Pb-glass detectors constructed by
the IHEP, Protvino group for the E-704 experiment at Fermilab.

the top and bottom calorimeters (above and below the beam
pipe) were similar to the south calorimeter.
