Use of ITER CODAC Core System in SPIDER Ion Source

In February 2011 ITER released a new version (v2) of the CODAC Core System. The SPIDER Ion Source experiment is the first experiment planned in the ITER Neutral Beam Test Facility under construction at Consorzio RFX, Padova, Italy. As the final product of the Test Facility is the ITER Neutral Beam Injector, we decided to adhere from the beginning to the ITER CODAC guidelines. Therefore the EPICS system provided in the CODAC Core System will be used in SPIDER for plant control and supervision and, to some extent, for data acquisition. In this paper we report our experience in the usage of CODAC Core System v2 in the implementation of the control and data acquisition (CODAS) system of SPIDER and, in particular, we analyze the benefits and drawbacks of the Self Description Data (SDD) tools.
