GEAR FOR PRECISION TURN OF ANISOTROPIC SAMPLE WITH REGARD TO TWO ORTHOGONAL AXES Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: invention refers to measurement of variable magnetic quantities of substances based on electron paramagnetic resonance. Gear for precision turn of anisotropic sample with regard to two orthogonal axes has case with flange for connection of cryostat of spectrometer, two mobile discs with circular limbs of angle of turn on their outer sides and verniers corresponding to limbs, two mechanisms of precision turn of mobile discs, tension filament, tubular carrier of sample holder, cylindrical sample holder, sample carrier fixed inside hollow cylindrical holder. Ring embraced by tension filament is anchored outside cylindrical holder, working end of tubular carrier has groove corresponding to it. Gear provides for independent precision turn of anisotropic sample about two orthogonal axes in spectrometer in temperature interval from 3.8 to 450.0 K with precision of 10-15 angular minutes for turn about vertical axis and 30 angular minutes for turn about horizontal axis. EFFECT: increased precision in determination of angles of turn and expanded working range of temperatures. 3 dwg
