DEVELOPMENT OF RF REFERENCE LINE FOR THE LINEAR COLLIDER

The distribution system of the rf reference line for the linear collider is required to supply stable x-band(11.424GHz) rf reference signal over 25km length within 1o(0.25ps) stability. In order to realize the distribution system, an optical fiber link using a phase stabilized optical fiber was tested. The phase stabilized optical fiber has been employed at LEP, KEKB, etc.. This paper describes the proposed hardware system and result of the preliminary test of the feedback system for the phase stabilization.
