SOLENOID COIL OF CESIUM ATOMIC BEAM TUBE Russian patent published in 2013 - IPC H01S1/06 

FIELD: electrical engineering.

SUBSTANCE: solenoid coil of cesium atomic beam tube contains two identical coils placed inside the system of magnetic screens at both sides of U-type SHF resonator along its axial plane and equispaced from it; each coil represents a rectangular frame of linear conductors with bridges and at each side of the frame bridges are divided into two equal parts and incurved smoothly perpendicular to axial plane of the resonator, at that one part is incurved in direction to the resonator while the other one in the opposite direction; incurve height towards the resonator h1 and incurve height in the opposite direction 2 are defined be the following conditions: 2≤h1/H≤0.6, 0.4≤h2/H≤0.8, where H is the distance between frames. Ratio of the frame width S and distance between frames H is equal to H/S=tg30°.

EFFECT: capability to decrease of magnetic frequency shift and increase of frequency stability for cesium atomic beam tubes.
