| Abstract: | The H maser is an essential frequency reference standard for radio astronomy. This paper provides information about the design and specifications of a new generation of the H maser for the Chinese mobile VLBI stations, including the improvement of the cavity bulb, magnetic shields and atomic beam optics. The performance measurements show that the frequency stability is a little better than 1*E 14 for time interval from 80 s to 1 day. |
| Keywords: | hydrogen maser frequency stability VLBI time synchronization |
