UNILAC is able to accelerate ions from hydrogen to ura-nium up to 20 MeV (p⁺) and 13 MeV/u (uranium). The main focus of the recent upgrade measures is to meet the FAIR requirements and to provide reliable and long term beam operation conditions. Besides post stripper upgrade and upgrade of the UNILAC controls, a particular atten-tion is paid to improve the performance of the High Current Injector (HSI) [1-7] and to intensify spare part management for the ageing accelerator. In order to en-sure operational reliability, the main focus lies on exten-sive spare part management and replacement of outdated equipment. Modified beam dynamics design for the frontend system and the use of advanced technologies are needed to improve the UNILAC performance. Among other things, a modified Low and Medium Energy Beam Transport section design for the HSI and installation of reliable (non-destructive) high intensity beam diagnos-tics devices are in progress. This paper addresses the status of current development efforts and specific plans for the UNILAC upgrade.
