Abstract

The authors have constructed and tested seven projective scintillating fiber-copper absorber hadron calorimeter towers for high-energy hadron collider detectors. Each tower contained 2.25% by volume scintillating fibers, embedded between copper laminations, 10.6 λ deep. A hadron energy resolution of σ/E=91%/√E was obtained. Pions exhibited uniform response when scanned across boundaries between modules and through a range of incident angles with respect to the fibers. The e /π ratio is 1.08±0.02 for energies between 10 and 20 GeV, with a response of ~60 p.e./GeV. The muon Landau distributions well-resolved from pedestals were observed
