Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2005. Includes bibliographical references (p. 63-67). In this thesis, the aging and the rejuvenation of an ATLAS proportional drift tube are described. Firstly, the Diethorn model of gain is tested using pressure and sense-wire voltage measurements. The drift tube was then aged using P10 gas (Ar:CH₄ 90:10) and a small amount of Si oil vapor, with a tube section of radius [approx.] 1 cm being subjected to UV radiation. An aging current of 30[mu]A was maintained and after the accumulation of 21 coulombs on the wire, the tube gain decreased to less than 70%. Subsequently, the tube was rejuvenated by the treatment with Ar:0₂ 99:1 gas, at reverse wire potential and an reverse "rejuvenation" current of 30[mu]A. Rejuvenation was successful after the accumulation of the equivalent of 3C from this current. by Yue Shi.
