Tau-Charm factory vacuum chamber design
The present article gives a description of the vacuum chamber required for a high luminosity electron e(+)-e(-) collider Tau-Charm factory. The beam lifetime, which is limited by the single particle collisions with molecules of the residual gas, is estimated. The synchrotron radiation gas loading is studied for the Tau-Charm factory vacuum chamber. The effect of various cleaning procedures on the outgassing behavior of samples of the chamber wall is studied. It is shown that a cleaning procedure by a suitable NaOH etching gives the best results of the tested techniques for minimizing of contaminations and outgassing rates.
