He3 solenoid magnetometer

摘要

A magnetometer having an enclosed cell containing He3 therein for receiving light from a light source, a light source for directing light to the enclosed cell along a predetermined path, a single pick-up coil containing therein the light source and the enclosed cell, a solenoid containing the pick-up coil therein and a data collection system coupled to the pick-up coil. The light source is a source of circularly polarized light and can comprise a He4 cell and an optical system and a circular polarizer disposed serially between He4 cell and enclosed cell containing He3. The predetermined path of the light source, the enclosed cell and the pick-up coil are disposed along the axis of the solenoid. The light source can also be a laser.
