SENSITIVE BROAD BAND ALTERNATING MAGNETIC FIELD DETECTOR, AND ITS USE AS A MEASURING APPARATUS

摘要

The sensor makes it possible to increase the performances, particularly from the sensitivity and frequency band standpoints, by means of a coaxial helical coil, matched to the connecting end to an auxiliary current measuring apparatus. At each turn, a portion of the external conductor is bared and equipped with elements for matching to the characteristic impedance in order to compensate the breaks caused in this way.
