Design and evaluation of a 10-mA DC current reference standard

A new DC current reference standard has been developed for high- current power converter calibration in the large hadron collider (LHC) project at the European Organization for Nuclear Research (CERN). This standard provides a near ideal 10-mA DC current with long-term drift of one part in 10/sup 6/...

Descripción
Sumario:A new DC current reference standard has been developed for high- current power converter calibration in the large hadron collider (LHC) project at the European Organization for Nuclear Research (CERN). This standard provides a near ideal 10-mA DC current with long-term drift of one part in 10/sup 6/ per year. The paper describes the requirements and the detailed design and evaluation of the unit. Since similar 10-V standards are commercially available, the paper concentrates on the unique current output capability of this device. (4 refs).
