Time Measurements with the CALICE Analogue Hadronic Calorimeter Prototype — •Lorenz Emberger for the CALICE-D collaboration — Max-Planck-Institut für Physik

One of the main design drivers for detectors at future energy-frontier e⁺e⁻ colliders is the precise determination of the energy of particle jets. This is achieved with detector designs optimized for particle flow algorithms.

CALICE is an R&D collaboration focussed on the development of highly granular calorimeters optimized to aid this paradigm by providing high spatial resolution. The Analogue Hadronic Calorimeter (AHCAL) is one of the detector concepts based on scintillating tiles read out by Silicon Photomultipliers. This calorimeter provides high spatial granularity and single-cell timing in order to enhance the particle separation and background rejection capability.

A 22000 channel technological prototype has been constructed and extensively tested in particle beams at CERN in 2018. This contribution is focussed on the time analysis of the data taken in the course of these test beam campaigns. It will touch upon the correction of electronic effects caused by the read-out chip and report on the achievable hit time resolution.
