Abstract

A prototype of a dual-readout calorimeter using brass capillary tubes surrounding scintillating and clear plastic optical fibres was tested using beams of particles with energies between 10 and 100 GeV produced by the CERN SPS. The scope of the test was to characterise the performance of the tube-based detector response to positrons in terms of linearity, energy resolution, and lateral granularity. After calibrating the detector and processing the output signal to correct for the energy dependency on the particle impact point, the linearity of the measurement was found to be better than 1\%. The positron response was compared to that predicted by a Geant4-based simulation, finding good agreement both in terms of energy resolution and shower profile. The detector resolution was estimated to be well described by a stochastic term of 14.5\% with a negligible constant term.
