Results on the performances of two hadron calorimeter prototypes for the ALICE experiment are presented. The two prototypes are made of brass and copper as passive material and PMMA fibres, arranged in a spaghetti calorimeter geometry, as active material. The calorimeters were tested at the CERN SPS, using hadron and positron beams of variable momentum in the range 50-200 GeV/c. The main features of the detectors, such as linearity, energy resolution and uniformity of response with respect to the beam impact point on their front face, are presented. The experimental results are compared to Monte Carlo simulations. (C) 2001 Elsevier Science B.V. All rights reserved.

Abstract
Results on the performances of two hadron calorimeter prototypes for the ALICE experiment are presented. The two prototypes are made of brass and copper as passive material and PMMA fibres, arranged in a spaghetti calorimeter geometry, as active material. The calorimeters were tested at the CERN SPS, using hadron and positron beams of variable momentum in the range 50-200 GeV/c. The main features of the detectors, such as linearity, energy resolution and uniformity of response with respect to the beam impact point on their front face, are presented. The experimental results are compared to Monte Carlo simulations. (C) 2001 Elsevier Science B.V. All rights reserved.
