Abstract :
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 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 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 Philips XP2020 photomultipliers
