  The new Gamma Beam System (GBS) under construction in Magurele (RO) by the consortium EuroGammas led by INFN, as part of the ELI-NP project, can provide gamma rays that open new possibilities for nuclear photonics and nuclear physics. In the ELI-GBS, gamma rays are produced by means of Compton back-scattering to get mono-chromaticity (0,1% bandwidth), a high flux (1013 photon/s the highest in the world), tunable directions and energies up to 19 MeV. Such gamma beam characteristic is obtained when a high-intensity laser collides a high-brightness electron-beam with energies up to 720 MeV. In order to increase the gamma beam flux, the electron beam operates at a repetition rate of 100 Hz in a multi-bunch mode: trains of 32 bunches, 16 ns apart, interact with the laser pulse recirculated 32 times through the interaction point. The EPICS Control System collects data from all sub-systems, constantly monitoring to ensure the safety of the ELI-GBS facility. This paper describes all the aspects of the ELI-GBS turn-key Control System, such as hardware integration, micro-bunches diagnostics, high level applications, the data network and the pico-second timing system.

The goal of the MYRRHA project is to demonstrate the technical feasibility of transmutation in a 100 MWth Accelerator Driven System by building a new flexible irradiation complex in Mol (Belgium). The MYRRHA facility requires a 600 MeV linear accelerator delivering a maximum proton flux of 4 mA in continuous operation, with an additional requirement for exceptional reliability. The control system of the future MYRRHA linac will have an essential role to play in this extreme reliability scenario. On the one hand the intrinsic reliability of the entire control system must be ensured. On the other hand control system will have to take up very high level duties of complex decision taking. This paper summarizes the ongoing developments for the concept design of such a control system. The related experimental activities performed and planned around the MYRRHA injector platform (ECR ion source + LEBT + RFQ) will also be described.

  This article presents a machine interlock system (MIS), designed and developed in collaboration between SINAP and Cosylab. The design is based on the experience and requirements of different accelerator facilities around the world, with the goal of providing, out of the box, the flexibility, reliability, availability, determinism, response speed, etc., which facilities need for a Machine Protection System (MPS). The goal of the MIS platform is to provide a reliable tool, which covers all the common MIS behaviour, required by an MPS designer. The system is based on a proven hardware platform, uses radiation-tolerant FPGAs, has built-in redundancies for power supply, hardware components and logic and is configurable from EPICS. We present several design principles that were used and explain the features and principles of application. Furthermore, we present the system architecture, from hardware and firmware to software. The MIS system is currently being installed at the BNCT facility at the Ibaraki Neutron Medical Research Center in Japan and is planned in the treatment interlock system of APTRON, the Advanced Proton Therapy Facility in Shanghai, China.
