Descripción
Sumario:The ALICE Zero-degree Calorimeters (ZDC) are quartz-fiber spaghetti calorimeters that exploit the Cherenkov light produced by the shower particles in silica optical fibers. This technique offers the advantages of high radiation $9 hardness, fast response and reduced lateral dimension of the detectable shower. In addition, quartz-fiber calorimeters are intrinsically insensitive to a radio-activation background, which produces particles below the Cherenkov $9 threshold. Two prototypes of the proton calorimeter, named ZP2 and ZP7, have been constructed with different geometrical and mechanical characteristics. They are both equipped with polymethylmethacrylate (PMMA) fibers read by 4 or 2 $9 Philips XP2020 photomultipliers. (6 refs).
