ELECTRON BEAM PARAMETER MEASURING DEVICE Russian patent published in 2025 - IPC G01T1/29 

FIELD: acceleration equipment.

SUBSTANCE: device for measuring parameters of an electron beam comprises a radiation source, a polariser, a radiation recorder, a fibre-optic cable for inputting light radiation into a polarization converter and for transporting the converted light radiation to the recorder, wherein the sensor is made in the form of a shielded multiturn circuit of a magnetically sensitive light guide from a special optical fibre, inside which an electronic conductor is placed, in the sensor housing there are holes for passage of light radiation to the measuring circuit, which includes a mirror, a polarization converter, a birefringence modulator, a fibre-optic circulator and an electronic processing unit.

EFFECT: high sensitivity of the sensor, ensuring stability of its operation when physical conditions change in the zone of its operation, avoiding the need for its precision installation.
