A reference standard system based on DC current

The Large Hadron Collider (LHC) particle accelerator project will require an accuracy of similar to 10**-**6 in the control of the current to the superconducting magnets. A new infrastructure for calibration is being built at CERN based on DC current reference standards rather than voltage. The pape...

Sumario:The Large Hadron Collider (LHC) particle accelerator project will require an accuracy of similar to 10**-**6 in the control of the current to the superconducting magnets. A new infrastructure for calibration is being built at CERN based on DC current reference standards rather than voltage. The paper describes the rationale, the infrastructure, the transfer methods and the performance.
