Outline• Introduction to Quartz Calorimetry• Quartz as radiation hard material• Quartz Calorimeters for the CMS Detector– Quartz Fiber Calorimeters• PPP1 -- Prototype•HF– Quartz Plate Calorimeters•Castor• QPCal Prototype• ConclusionTHE UNIVERSITY OF IOWAY. Onel, CALOR2006, Chicago2
Introduction• The detector is intrinsically radiation hard at the required level(hundreds of MRads)• The detector, for all practical purposes, is sensitive to theelectromagnetic shower components (ρ M)• It is based on Cherenkov radiation and is extremely fast (< 10 ns)• Low but sufficient light yield ( 1 / nTHE UNIVERSITY OF IOWAY.
