A hydrogen maser frequency standard for timekeeping has |
|
been worked at Shanghai Observatory. The maser employs a |
|
fast cavity auto-tuner, which can detect and compensate |
|
the frequency drift of the high-Q resonant cavity with a |
|
short time constant by means of a signal injection |
|
method, so the long term frequency stability of the maser |
|
standard was greatly improved. This paper describes the |
|
cavity auto-tuning system and some maser data obtained |
|
from the atomic time comparison. |
