Abstract: The SPIDER central interlock is a centralized electronic system to coordinate the protection functions within the SPIDER experiment (Source for the Production of Ions of Deuterium Extracted from an RF plasma), i.e. the full-size ion source prototype of the ITER Neutral Beam Injector. Due to the system time requirements, the SPIDER central interlock has been implemented by using PLCs for the slow functions (100 ms reaction time from fault detection to protection command emission) and National Instruments CompactRIO for the fast functions (10 μs from fault detection to command emission). The paper describes in detail the system hardware and software implementation. The results of the first tests and commissioning are reported with particular focus on the implementation, execution, and performance of the interlock fast functions.
