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. Results obtained by using the chamber with electron and muons in a beam test area at CERN are reported and compared with the simulations.
