COMET (Coherent Muon to Electron Transition) is an experiment designed to search for the process of the neutrinoless, coherent transition of a muon to an electron in an aluminum atom, which will be implemented using the proton beam of the J-PARC accelerator complex, Japan. One of the main detectors of the COMET experiment is a straw tracker made of thin-walled drift tubes. A straw tube is a single-channel gas drift tube, the time parameters of which will determine the accuracy of measuring the momentum of a 105 MeV electron in the experiment. To study the time characteristics of thin-walled (12 μm) aluminized straw tubes with a diameter of 5 mm, a precision measurement system was developed and measurements of the time resolution, drift velocity, nonlinearity of the parameters over the cross-section were performed, the R-T dependence for the Ar/CO&sub(2) (60/40) pre-mixed gas mixture was obtained. This setup also allows studying the time parameters for other gas mixtures.
