The physics program of the International Linear Collider requires precise knowledge of the luminosity weighted average polarisation at the electron-positron collision point. One crucial element of the ILC polarimetry concept is the use of Compton-Polarimeters measuring before and behind the collision point. It is foreseen to use Cherenkov detectors to measure the Compton scattered electrons or positrons in the polarimeter chicanes. In this talk, a possible design for a quartz-based Cherenkov detector for this purpose will be presented.
