| Abstract: | In this paper the time performance of the precision drift tube at high pressure has been studied. The time spectrum of the drift electrons and the (r-t) relationship between the distance from the charged particle track to the anode wire and the drift time have been measured via both radioactive sourceand cosmic rays. Some factors which influence the r-t relationship have been also investigated. The fitting parameters of the drift time spectrum have been analyzed and the r-t relationship has been obtained from the drift time spectrum by using integral method. |
