Instrument Control and Data Acquisition System of the ILL High Flux Reactor Neutron Beam Instruments

Nearly 40 neutron beam instruments are now in routine operation at the thermal neutron research reactor of the trinational Institut Laue-Langevin in Grenoble, France. They are run in a highly automated way by a 3-level system : Dedicated, on-site instrument control and data acquisition electronics systems (level 1), and dedicated, on-site minicomputers (level 2) which are linked to the central scientific computer (level 3).
