Abstract :
The performance of three similar trapped ion frequency standards, which use mercury in a hyperboloidal Paul trap, is presented. Initially, frequency deviations well below 10-14 rms were observed on time scales of 1-10 days, but the standards later underwent frequency variations of up to 10-12 s/s, which are probably due to impurity effects
