The end-of-life of many components brought the need for a redesign of our main Control System Front-End - the SCU (Scaleable Control Unit). It was a chance to make improvements and use more powerful state-of-the-art core components. [...]

An electron beam test stand has been designed and constructed at CERN as part of the High Luminosity LHC (HL-LHC) project, in collaboration with the ARIES project, to test components related to the Hollow Electron Lens (HL-LHC) and the GSI Space Charge Compensation Electron Lens (ARIES). This comprehensive test facility incorporates normal conducting solenoid magnets, including horizontal and vertical correctors, which generate fields of fractional Tesla magnitude. [...]

Facility for Antiproton and Ion Research (FAIR) is going to make wide use of superconducting magnets for its components: the SIS100 synchrotron, the Superconducting Fragment Separator (SFRS) and Atomic, Plasma Physics and Applications (APPA) experiments. For all these magnets, uniform quench detection (QuD) electronics have been developed to protect them in case of uncontrolled loss of superconductivity. [...]

For the future Facility for Antiproton and Ion Research (FAIR), which is currently under construction, a new Control System is being developed and already used at major parts of the GSI facility. The central component for Settings Management within the FAIR Control System is based on CERN’s framework 'LHC Software Architecture' (LSA) and enhanced by FAIR specific features. [...]

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 superconducting continuous wave (cw) heavy ion HElmholtz LInear ACcelerator (HELIAC) is intended to be built at GSI in Darmstadt. With its high average beam current and repetition rate, the HELIAC is designed to fulfill the requirements of the super heavy element (SHE) research user program and the material sciences community at GSI. [...]

A FAIR injector linac for the future FAIR facility is under construction. In order to meet the requirements for copper plating of the CH-cavities, a variety of tests with dummy cavities has been per-formed and compared to simulation. [...]

The UNILAC will serve as injector linac for heavy ion beams for the future FAIR, with the commissioning being anticipated in 2025. One of the crucial steps in the course of acceleration along the UNILAC is the stripping of the ions by a gas stripper in front of the main linac. [...]

In accelerator labs like GSI/FAIR, automating complex systems is key for maximizing physics experiment time. This study explores the application of a data-driven model predictive control (MPC) to refine the multi-turn injection (MTI) process into the SIS18 synchrotron, departing from conventional numerical optimization methods. [...]

The complexity of the GSI/FAIR accelerator facility demands a high level of automation in order to maximize time for physics experiments. Accelerator laboratories world-wide are exploring a large variety of techniques to achieve this, from classical optimization to reinforcement learning. [...]
