LEAD SCINTILLATING FIBER (SPAGHETTI) CALORIMETRY/

The Lead/Scintillating fibre (''Spaghetti'') calorimetry technique was extensively studied, over the last 7 years, in the framework of the L AA project. Important developments were achieved both for use in elect romagnetic and hadronic calorimetry. This paper contains an overview o f results on speed, linearity, energy resolution, gaussian response li ne-shape, radiation damage, fast electron/pion discrimination capabili ties and spatial separation capabilities. Other significant results re ported on are: negligible energy resolution constant term, complete he rmiticity, response uniformity below the percet level even across modu le boundaries, self supporting projective structure, fast triggerabili ty.
