Maximum safety for research laboratory
HIMA delivers HIMatrix system for medical 150kV implanter system of the
Maier-Leibnitz Laboratory which is part of the Ludwig Maximilians Univer-sity and the Technical University of Munich
(Brühl, 13th July 2006) - For the protection of persons and property, a safety system by HIMA Paul Hildebrandt GmbH + Co KG has been installed in a new system used for surface treatment of medical implants at the Maier-Leibnitz Laboratory (Munich). HIMA's automation concept is based on a F20 safety-related controller and three remote I/Os from the HIMatrix range. The HIMatrix system reliably monitors the final positions of the earthing rod, the safety gate, the emergency shutdown switches and the safe shut-down of the high-voltage power units in the system.
When the system is in operation, there is a potential risk of electric shock. Moreover, the high voltages may cause crossovers. The safety system has to be able to communicate safely across the voltage levels 0 V, 150 kV and 180 kV. In addition, an interface to a non-safety re-lated PLC of a different manufacturer is required.
As the HIMatrix controller can communicate openly with systems from other manufacturers, the HIMA system can easily adapt to the required system structure. The data transmission between HIMatrix components is safely implemented by means of fibre optics. This is to ensure that the required electrical isolation can be reached. The safety-related networking of the system is performed via safeethernet from HIMA, ful-filling yet another customer requirement.
HIMA delivered the hardware and supported the customer during the concept design and programming of the safety system.
The Maier-Leibnitz Laboratory is a joint institution of the Ludwig Maxi-milians University and the Technical University of Munich, which carries out research and training in the field of nuclear and particle physics. Today's focus of the scientific activities of the accelerator laboratory is more on interdisciplinary research in the fields of material analysis, medicine, ultra-sensitive trace analysis and radiation protection than on nuclear physics. The medical implants, into which the new system in-serts radioactive radiators, are used for ENT and eye operations. They keep surgical cuts open or prevent the openings from growing back to-gether.
