Developments in the High Precision Control of Magnet Currents for LHC

The LHC will require over 1700 magnet power converters, some of which will need an unprecedented precision of about 1 ppm (of 13 kA). This paper presents the approach taken, prototype methods, initial results and charts future design directions. These results confirm that such performance can be obt...

Sumario:The LHC will require over 1700 magnet power converters, some of which will need an unprecedented precision of about 1 ppm (of 13 kA). This paper presents the approach taken, prototype methods, initial results and charts future design directions. These results confirm that such performance can be obtained reliably and at a reduced cost compared to conventional methods. Developments of a real-time controls infrastructure needed to support on-line beam feedback are outlined.
