Radiation Hardness of Efratom M-100 Rubidium Frequency Standard
Abstract
The effects of nuclear radiation on rubidium gas cell frequency standards and components are presented. including the results of recent tests where a continuously operating rubidium frequency standard (Efratom, Model M-100) was subjected to simultaneous neutron/gamma radiation. At the highest neutron fluence [7.5 x 10(12) n/cm2] and total dose [11 krad(Si)] tested, the unit operated satisfactorily; the total frequency change over the 2.5 hour test period due to all causes, including repeated retraction from and insertion into the reactor, was less than 1 x 1O(-10), The effects of combined neutron/gamma radiation on rubidium-frequency- standard physics-package components were also studied, and the results are presented.
