Current status of SPIDER CODAS and its evolution towards the ITER compliant NBI CODAS

The ITER Neutral Beam Test Facility currently under construction at Padova, Italy, consists of two experiments: SPIDER to test the ITER-size ion source with -100 kV acceleration potential, and MITICA to test the full ITER Neutral Beam Injector operating at -1 MV acceleration potential. While the former represents an intermediate step, also finalized to the ITER Diagnostic Neutral Beam, the latter will represent the final design and implementation of the full prototype of the ITER Heating Neutral Beams. Consequently, for the Control and Data Acquisition System (CODAS) of SPIDER there are no requirements for compliance with ITER CODAC, whereas the MITICA Heating Neutral Beam Plant System will comply with the ITER directives for CODAC management because that final system will be eventually integrated in ITER. SPIDER CODAS is currently under commissioning and the integration of the different frameworks that operate in an integrated way proved successful. The experience and solutions gained in SPIDER CODAS development will be reused as far as possible in MITICA and to provide at the same time the required CODAC compatibility, a set of ITER-like layers (networks) will be defined, using exactly the same protocol defined for ITER interfaces.
