Scintillator studies for the CALICE Analogue Hadronic Calorimeter and the DUNE ND-GAr Electromagnetic Calorimeter — Andrea Brogna2, Peter Bernhard2, Volker Büscher1, Karl-Heinz Geib1, Asma Hadef1, •Antoine Laudrain1, Lucia Masetti1, Marisol Robles Manzano1, Anna Rosmanitz1, Christian Schmitt1, Alfons Weber1, and Quirin Weitzel2 for the CALICE-D collaboration — 1Institut für Physik, Johannes Gutenberg Universität, Mainz — 2PRISMA Detector Lab, Johannes Gutenberg Universität, Mainz
The CALICE Analogue Hadronic Calorimeter (AHCal) is designed as an imaging calorimeter optimised for particle flow algorithms. It features a high granularity and timing resolution, with plastic scintillator active layers and SiPM readout. The concept of Megatile is developed to ease the assembly of a large scale detector, separating a large piece of scintillator with a glue + TiO2 mixture and gluing a reflective sheet on both sides instead of individually wrapping smaller tiles in a reflective foil for each channel.
In the DUNE ND-GAr, neutron energy is reconstructed using the time-of-flight information provided by the Electromagnetic Calorimeter (ECal). The ECal must therefore provide neutron identification with high granularity and timing, making the AHCal with Megatiles a potential design candidate. Pulse shape discrimination is envisaged as a means to discriminate photon from neutron interaction in the ECal. A setup to study the PSD performance of various plastic scintillators with SiPM readout has been set up and first results will be presented.
