Quartz fibers a new calorimetry for multi-TEV very forward physics

A new calorimetry technique based on shower sampling of Cherenkov light in optical fibers is presented. Fast response, excellent radiation hardness, insensitivity to neutrons, shower core detection and this technolgie's static (no gas, no liquids) properties make it an excellent candidate for Very Forward Calorimetry (VFCal) for the LHC.
