Test of PB/SCIFI Electromagnetic Calorimeter Prototypes with Low Energy Photons at LADON

Key Points

The aim is to evaluate the performance of PB/SCIFI electromagnetic calorimeter prototypes using low energy photons.
Conducted measurements on small size calorimeter modules with plastic scintillating fibers and lead.
Investigated calorimeter properties under head-on and side-on photon incidence conditions.
Tested photons in the energy range of 20-80 MeV.
Achieved an energy resolution of 4.8%/\sqrt{E[GeV]} under lateral photon incidence.
Included a 2%/\sqrt{E[GeV]} term for photoelectron statistics impacting measurement accuracy.

Abstract

In this work we report the complete set of measurements carried out at LADON on small size calorimeter modules composed of a uniform array of plastic scintillating fibers and lead (50: 35 by volume ratio) for photons in the energy range 20-80 MeV. Calorimeter properties for both head-on and side-on incidence conditions have been investigated. With photons hitting the fibers laterally, an energy resolution of 4. 8%/ is obtained. This figure includes a 2%/ term added in quadrature due to the photoelectron statistics.
