N1 - Funding Information:
We are very much indebted to the LAA project leader, Prof. A. Zichichi, for his warm interest and encouraging support for this project. We are grateful to Dr. P. Jenni, who helped us in many ways, in particular when running the beam tests. The work described in this paper would have been impossible without the outstanding technical support provided by our technicians O. ba, S. Bricola, IM. Chapuis, A. Freddi, G. Iuvino, G. Pontoriere, L. Rose-Duulcina, G . Sannier, A. Sigrist and V. Vanzanella. Financial support from the Istituto Nazionale di Fisica Nucleate to the Cagliari, Napoli and Pavia groups is acknowledged. And finally, we are grateful to the staff of the SPS for the excellent beam conditions provided during our tests.

N2 - In the framework of the LAA project, prototypes for a new type of calorimeter, intended for the detection of both electromagnetic (e.m.) and hadronic showers, muons and missing energy (e.g. neutrinos) at high-luminosity multi-TeV pp colliders, were tested. The detector consists of scintillating plastic fibres embedded in a lead matrix at a volume ratio 1:4, such as to achieve compensation. The optimization of the construction of the detector modules is described, as well as the performance concerning e.m. shower and muon detection and e/π separation. We used electron, pion and muon beams in the energy range 10-150 GeV for this purpose. For the energy resolution of electrons we found 13%/trE, with a constant term of 1%. The signal uniformity was better than 3% over the total surface of projective modules. The signal linearity for e.m. shower detection was better than 1%, and the e/π separation was better than 5 × 10-4 for isolated particles. Channeling effects are negligible, provided that the angle between the incoming particles and the fibre axis is larger than 2°.
