Conference paper

Abstract

The shape of the starage bulb in the H-maser cavity determines the value of the filling factor η’ defined as
$$ \eta = \frac{{\left\langle {{H_Z}} \right\rangle _B^Z \bullet _B^V}}{{{{\left\langle {{H^2}} \right\rangle }_C} \bullet _C^V}} $$
Where symbols have their usual meanings and the z direction is that of the static bias field.
