DENISE is an acronym for Deuterium Negative Ion Source Experiment and originated in FOM the Institute for Atomic and Molecular Physics in DCU where it is being recommissioned as a test bed for the production and extraction of negative hydrogen ion for use in proposed nuclear fusion reactors. These reactors require the neutralisation of particle beams of up to hundreds of amps and energies of about IMeV for use in Neutral Beam Injection (N.B.I.). The objective of this project was to automate the multicusp volume ion source called DENISE. Automation is the technology concerned with the application of mechanical, electronic, and computer-based systems in the operation and control of production. This process of technological development lends real-time monitoring and quick error detection and correction to parameters and components that need to be controlled. Another feature is the ease of use and the attraction of the safety features that are inherent in this technology. The parameters and components that are to be controlled are decided upon and the methods in which this is to be achieved discussed. The control system consists of a software/hardware interface to the pressure system, the cooling system and the pumping system. The Windows software monitors and displays the status of the physical system. An optoisolated electronic interface circuit allows control of the physical processes.
