The development of an intense source of neutrons with the spectrum of DT fusion reactions is indispensable to qualify suitable materials for the First Wall of the nuclear vessel in fusion power plants. The FW, overlap of different layers, is essential in future reactors; they will convert the 14 MeV of neutrons to thermal energy and generate T to feed the DT reactions. IFMIF will reproduce those irradiation conditions with two parallel 40 MeV CW deuteron Linacs, at 2x125 mA beam current, colliding on a 25 mm thick Li screen flowing at 15 m/s and producing a n flux of 10¹⁸ m2/s in 500 cm³ volume with a broad peak energy at 14 MeV. The design of the control architecture of a large scientific facility is dependent on the particularities of the processes in place or the volume of data generated; but it is also tied to project management issues. LHC and ITER are two complex facilities, with ~10⁶ process variables, with different control systems strategies, from the modular approach of CODAC, to the more integrated implementation of CERN Technical Network. This paper analyzes both solutions, and extracts conclusions that shall be applied to the future control architecture of IFMIF.

	The development of an intense source of neutrons with the spectrum of DT fusion reactions is indispensable to qualify suitable materials for the First Wall of the nuclear vessel in fusion power plants. The FW, overlap of different layers, is essential in future reactors; they will convert the 14 MeV of neutrons to thermal energy and generate T to feed the DT reactions. IFMIF will reproduce those irradiation conditions with two parallel 40 MeV CW deuteron Linacs, at 2x125 mA beam current, colliding on a 25 mm thick Li screen flowing at 15 m/s and producing a n flux of 10¹⁸ m2/s in 500 cm³ volume with a broad peak energy at 14 MeV. The design of the control architecture of a large scientific facility is dependent on the particularities of the processes in place or the volume of data generated; but it is also tied to project management issues.
