Conference paper


Thermal noise limits the precision of H maser standards out to averaging times of order 104 seconds, beyond which it is limited by other factors despite attempts to stabilize everything that could cause a frequency shift. This paper examines the dependence of the hydrogen maser frequency on factors other than thermal noise, in order to provide a guide to improving stabilization efforts.
