Abstract

We propose extending parallel fiber dual readout calorimetry to tiles, more applicable to many future experimental requirements, with superior energy resolution. Monte Carlo (MC) studies indicate that a tile dual calorimeter including an integral Cerenkov-compensated e-m front end and further longitudinal segmentation, not possible with parallel fibers, has equivalent or better resolution. Besides comparison and tuning with dual tile calorimeter data, a MC can be extended to study other dual and then multiple tile sensors including tiles with higher contrast to em-hadron shower fluctuations with low refractive indices (much lower than quartz or plastic), transition radiation, secondary emission, hydrogenous/non-hydrogenous ionization-sensing, and neutron and ion-fragment sensing tiles for improving dual readout not available with fibers, and beyond to triple or more readout. For example, secondary emission tiles (like dynodes) are very sensitive to ion fragments and low energy neutrons. We suggest MC studies for adding Cerenkov and other tiles to Particle Flow/High Granularity tile calorimeters such CALICE and planned in CMS & ATLAS Phase III upgrades, groups studying future machine(ee,pp,ep) detectors, b-physics, tagged neutrino experiments, and space-based calorimeters.
