SQUID SYSTEM HAVING INCREASED FLUX VOLTAGE TRANSFER FUNCTION

摘要

The invention relates to a SQUID system having an increased flux voltage transfer function. The object of disclosing a circuit configuration providing an increased flux voltage transfer function of a SQUID, wherein the measurement sensitivity of the system is noticeably increased and the required readout electronics are simplified, is achieved in that at least one SQIF (4) is provided as an amplifier circuit and is connected downstream of the first SQUID (1), wherein a coupling coil (3) electrically connected to the first SQUID (1) is directly associated with all loops of the SQIF (4).
