Effect of weak magnetic field changes on the sensitivity of ultrapure germanium γ-detectors
Experimental data are presented indicating the effect of small changes of the earth’s magnetic field strength H on the efficiency of ultrapure germanium γ-detectors. With a reduction in H by 0.056 Oe and a simultaneous change in direction by 2.8°, the relative reduction of a planar director efficiency (with a vertical direction of the electric field applied to it) for recording γ-quanta with energy 88.03 keV is 0.00028 ± 0.00013.
