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 lambda deep. A hadron energy resolution of sigma /E=91%/ square root 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/ pi ratio is 1.08+or-0.02 for energies between 10 and 20 GeV, with a response of approximately 60 p.e./GeV. The muon Landau distributions well-resolved from pedestals were observed.ETX
