| 抄録 | This article introduces the current and future systems for the standard time generating and measurement system at the CRL. The features of these current working systems compared with the former ones are dual redundancy in the main part. It is effective to improve reliable and rapid reaction to emergency situations. The system is going to be moved to a new building next year and the current system is renewed on this opportunity. The new system will have many improvements such as an introduction of a hydrogen maser or multi-channel DMTD system, which enables it to realize a higher performance. |
