Requirements for the CLIC tracker readout

The requirement of precision physics and the environment found in the proposed future high-energy linear $e^{+}e^{−}$ collider CLIC result in challenging constraints for the silicon tracking detector. A track-momentum resolution of approximately $\sigma_{p_T}/p^2_T = 2\times10^{−5}$GeV${}^{−1}$ for high-momentum tracks has to be achieved in an environment with high rates of beam-induced background events. The current layout foresees a multi-layer tracking detector system arranged in a barrel and endcap geometry with a total surface of approximately 100 m${}^2$. This note describes the specifications for the tracker sensors and readout electronics.
