Description
The Tandem of Orsay was installed in 1973 with a control-command system (C&C) which was manual and cabled on a central writing desk. In 1993, the installation of the ion source ORION in the 15 MV terminal imposed the development of a new system of C&C. In 1997, this system was gradually extended to the whole accelerator. Since 2008 many problems occurred because various components became obsolete. In addition, all the designers are retired. So we have decided to develop a new C&C based on automaton. In January, 2011 a first test has been successfully achieved with the installation of an automaton in the terminal of the accelerator. For the first time we have put an automaton in a very perturbing environment. Indeed the central electrode of the accelerator can be raised up to 15 MV. Such an intense field can be maintained only by strengthening the electric insulation with an efficient gas, the hexafluoride of sulfur (SF6) under 8 atm.
