Ampegon AG delivers high voltage power supplies for heating ITER plasma gas
The Electron Cyclotron system at the ITER fusion reactor will be used to heat a hot plasma gas to over 100 million ºC, almost ten times the temperature at the core of the sun. Ampegon AG has been contracted to design, manufacture, install and commission the power supplies for the Electron Cyclotron system. The company is supplying 8 high voltage power supplies (55 kV/100 A) and 16 body power supplies (35 kV/100 mA) to be installed at the ITER site at Cadarache in France from 2019.
Fusion, the nuclear reaction that powers the sun and the stars, is a potential source of safe and virtually limitless energy. Harnessing fusion's power is the goal of the ITER project in France, which will be the key experimental step between today's fusion research machines and tomorrow's fusion power plants.
Ampegon AG has been contracted by Fusion for Energy (F4E), the organisation managing Europe’s contribution to ITER, to design, manufacture, install and commission the power supplies for the Electron Cyclotron Resonance Heating (ECRH) system, one of the plasma heating systems at ITER.
Power for fusion
The temperature inside the ITER fusion reactor needs to reach over 100 million ºC, almost ten times the temperature at the core of the sun. One of the heating systems that will be used to achieve the fusion reaction is the Electron Cyclotron system.
Manufacture and installation
Ampegon is supplying 8 high voltage power supplies (55 kV/100 A) and 16 body power supplies (35 kV/100 mA) to ITER. A strict requirement of the power supply system is that it must be designed to shut down in less than 10 microseconds.
The ITER organisations have approved the design of the power supply systems and Ampegon has started manufacturing and testing the equipment at their Swiss factory. Installation and commissioning at the ITER site in Caderache, France will take place from 2019.
With very high peak energy levels, accelerator and fusion facilities are dependent on a highly stable mains power supply and very low EMI figures. Ampegon technology keeps the mains consumption at a constant level and the system design results in low component stress and long component lifetime.
