STAR Forward Pi0 Detector Installation Progress
Installation of calorimeter south of beam on west tunnel
platform extension in STAR Wide Angle Hall. The calorimeter consists
a preshower consisting of an enclosed Pb sheet followed by
a seven element array of 3.7cm × 3.7cm × 45cm Pb-glass detectors.
a shower maximum detector (SMD) consisting of triangular
cross section scintillator strips. The SMD has two orthogonal planes.
a 7×7 matrix of Pb-glass detectors, individually wrapped
in aluminized mylar reflectors. Also visible in the pictures below
are optical fibers that transmit light from a blue light-emitting diode
to each Pb-glass detector.
