An ultra-low mass Tracking Chamber with Particle Identification capabilities is proposed for a future $e^{+}e^{-}$ collider.
Details about the construction parameters of the drift chamber including both the inspection of new material for the wires , of new techniques for soldiering the wires, the development of an improved schema for the drift cell and the choice of a gas mixture are described. The performance of the tracking are studied together with the Improved particle identification capabilities obtained by using a cluster counting technique.
