The current TRISTAN accelerator control system uses CAMAC as a front end electronics, and they are controlled by twenty five Hitachi minicomputer HIDIC 80’s which are linked with an N-to-N token ring network. After five years from now, these computers must be replaced. This is because of the life time of control system and we have to cope with the requirements imposed by our future project such as the KEK B-Factory and the main ring photon factory projects. The rejuvenation of this control has to be done under some constraints such as the lack of manpower, limited time and financing. First we review the problems of current control system, then the philosophy of the new generation control system is presented. Finally it is discussed how to move to the new generation control system from the current TRISTAN control system.

The main linac of Japan Linear Collider(JLC) will be operated at an X-band frequency of 11.424 GHz. The positioning of the X-band accelerating structures at JLG requires precise phase synchronisation over about 10 km. Temperature compensated fiber optic cables will be used for the transmission of the 11.424 GHz RF signal. The performance of this transmission line is described. Many timing signals will be also transmitted from the main control room, in which the master RF frequency generator will be situated, via this l.3 ¿m single mode fiber optic link. The outline of the timing system for JLC is given in this paper.
