This paper describes experiments carried out at the National Physical Laboratory using a hydrogen maser in comparison with a group of caesium standards which define the NPL time scale. A technique is developed for setting the maser and measuring its

THE accuracy of the unperturbed frequency of the hydrogen maser is limited by the uncertainty of the wall shift caused by the storage bulb coating1. Different samples of nominally the same material have been found to give different shifts2 and so it

The exploration and exploitation of the submillimetre and millimetre wave regions of the electromagnetic spectrum have progressed steadily over the last twenty years. Sophisticated Fourier spectroradiometric instrumentation, matching in performance t
