Cherenkov Detector Prototype & Testbeam 2009

Abstract

Precise knowledge of all beam parameters is crucial to fully exploit the physics potential of the International Linear Collider (ILC). A sufficiently accurate measurement of the beam polarisation can only be achieved using dedicated high energy Compton polarimeters combined with well-designed arrays of Cherenkov detectors. This note focuses on the design and detailed simulation of a suitable Cherenkov detector prototype and provides an overview of first results from a highly successful beam test period.
