LHC Magnet Power Circuits

Would expect all circuits to have been commissioned during hardware commissioning. Clearly their use in beam control will have also been tested in the machine checkout phase - ramp, squeeze, trim etc.

The information in the tables is extracted from the powering Database.   It is, however, re-organized in terms of end use - rather than location.
