TWO-CHANNEL SQUID-MAGNITOMETER WITH VARIABLE BASE

摘要

The invention relates to magnetometric engineering and is intended for measurement of magnetic materials in biological objects (human person or animal). Magnetometer proposed includes fiberglass plastic helium cryostat and two measuring probes that include SQUID-sensors of magnetic field and input antennae (gradient meters for magnetic flux). According to the invention antennae are displaced with respect to axes of probes, this makes it possible to change distance between antennae (base) through rotation of the probes in cryostat. This makes it possible to realize three modes of operation: 1) gradient measuring device of higher order (minimal base); 2) 1-channel magnetometer with reference channel (maximal base); 3) differential magnetometer (medium base). Technical result of the invention is in possibility of change of mode of operation of magnetometer.
