摘要

作者为高能强子对撞机探测器构建并测试了7个投影闪烁光纤-铜吸收体强子量热塔。每个塔包含2.25%的体积闪烁纤维，嵌入在铜层之间，深10.6 λ。得到了sigma /E=91%/平方根E的强子能量分辨率。当扫描穿过模块之间的边界和相对于光纤的一系列入射角时，介子表现出均匀的响应。能量在10到20 GeV之间的e/ pi比值为1.08±0.02，响应约为60 p.e./GeV。观测到从台座上很好地分辨出的μ子朗道分布

Copper-scintillating fiber hadron calorimeter tower prototypes

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.<>
