BPC(Beam Pipe Calorimeter)

• Structure: 24 layers of concentric lead (1 mm) and scintillating fiber (0.5 mm) sandwiches. 17.9 X0 effectively.
• Coverage: 59.5 mm < R <98.5 mm (1.9 deg < theta < 2.6 deg).
• Devided into 16 sectors in phi and 2 layers in theta.
• Photodiode readout.
• 5.4% energy resolution, 1.5 mm (in theta) and 2.0 mm (in phi) spatial resolution at 29 GeV.
