Abstract: The existing post-stripper DTL of the GSI UNILAC will be replaced with the new Alvarez 2.0 DTL to serve as the injector chain for the Facility of Antiproton and Ion Research (FAIR). The 10⁸.4 MHz Alvarez 2.0 DTL with a total length of 55 meters has an input energy of 1.36 MeV/u and the output energy is 11.32 MeV/u. The presented First-of-Series (FoS) cavity section with 11 drift tubes and a total length of 1.9 m is the first part of the first cavity of the Alvarez 2.0 DTL. After copper plating and assembly of the cavity the RF-conditioning started in July 2021. These proceeding gives an overview on the results of the successfully RF-conditioning to reach the necessary gap voltage for uranium operation including a comfortable safety margin.
