Cluster counting drift chamber as high precision tracker for ILC experiments

Precision measurements at the International Linear Collider on physics channels of crucial interest are demanding for resolution of the order of δpT/pT2=10-5GeV-1c up to momenta as high as 50GeVc-1. A light weight He-based drift chamber with full stereo wires is proposed together with a cluster counting technique, performing potentially better than state-of-the-art TPCs. Detailed studies on the implementation of cluster counting and realization of custom front-end electronics is in advancement. Experimental tools for space resolution measurements with 10μm precision is being set up, in preparation of an extensive program of cosmic rays and beam tests.
