The CMD-3 experiment has been operating at the VEPP-2000 electron–positron collider, at the Budker Institute of Nuclear Physics, since December 2010. Its main goal is to measure the hadronic cross sections necessary to evaluate the anomalous magnetic moment of the muon. The discrepancy between the theoretical calculations and the experimental results obtained at the Brookhaven experiments is approximately 3.7 σ. The comparison between the results of the new “g-2” experiment at Fermilab and the theoretical calculation thanks to the new experimental contributions from CMD3 would provide important contributions to this measurement, which could prove the existence of New Physics. A key element for the success the CMD3 experiment is the tracking detector, which is a drift chamber built in the year 2009 at INFN of Lecce. Because of aging effects, its replacement is necessary. This paper presents the innovative design for the new ultralight CMD3 drift chamber. •CMD3 experiment studies the anomalous magnetic moment of the muon.•The CMD3 new drift chamber is an ultralight multiwire drift chamber.•The goal is to maximize the transparency and minimize the multiple Coulomb scattering.•The mechanical design separates the gas containment from the wire support function.•The chamber will be equipped with cluster counting/timing readout techniques.
