  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.
