A spaghetti calorimeter (SPACAL) prototype with scintillating crystal fibres was assembled and tested with electron beams of energy from 1 to 5 GeV. The prototype comprised radiation-hard Cerium-doped Gd 3 Al 2 Ga 3 O 12 (GAGG:Ce) and Y 3 Al 5 O 12 (YAG:Ce) embedded in a pure tungsten absorber. The energy resolution was studied as a function of the incidence angle of the beam and found to be of the order of 10% / √ E ⊕ 1%, in line with the LHCb Shashlik technology. The time resolution was…
