Abstract

An optical fiber cable with highly stabilized transmission delay time and improved resistivity against irradiation was installed for the transmission of 508-MHz timing signal between the linac gun room and the TRISTAN AR. The optical system eliminated the frequent phase adjusting in the former coaxial transmission system required from the temperature change in a year. The use of this phase-stabilized optical fiber system will be effective in the precise transmission of timing signals in the acceleration systems. The slow timing system has managed the operation since January 1990. It gives more reliability and more flexibility.<>
