Abstract: The Alvarez-type post-stripper DTL at GSI accelerates intense ion beams with A/q = 8.5 from 1.4 to 11.4 MeV/u. After more than 45 years of operation it suffers from aging and its design does not meet the requirements of the upcoming FAIR project. The design of a new 10⁸ MHz Alvarez-type DTL has been completed and series components for the 55 m long DTL are under production. In preparation, a first cavity section as First of Series has been operated at nominal RF-parameters. Additionally, a prototype drift tube with internal pulsed quadrupole has been built and operated at nominal parameters successfully. High quality of copper-plating of large components and add-on parts has been achieved within the ambitious specifications. This contribution summarizes the current project status of Alvarez 2.0 at GSI and sketches the future path to completion.
