	In this paper, we report the conceptual design of control networks used in the control system for China initiative accelerator driven sub-critical (ADS) facility which consists of two accelerator injectors, a main accelerator, a spallation target and a reactor. Because different applications have varied expectations on reliability, latency, jitter and bandwidth, the following networks have been designed for the control systems, i.e. a central operation network for the operation of accelerators, target, and reactor; a reactor protection network for preventing the release of radioactivity to the environment; a personnel protection network for protecting personnel against unnecessary exposure to hazards; a machine protection network for protecting the machines in the ADS system; a time communication network for providing timing and synchronization for three accelerators; and a data archiving network for recording important measurement results from accelerators, target and reactor. Finally, we discuss the application of high-performance Ethernet technologies, such as Ethernet ring protection protocol, in these control networks for CIADS.

	Z. He, W. Cui, Y. Luo, X. Ting, H.S. Xu, L. Yang, X. Zhang, Q. Zhao IMP/CAS, Lanzhou, People's Republic of China
	In this paper, we report the design of the control system for the spallation target in China initiative accelerator driven sub-critical (ADS) system, where a heavy-metal target located vertically at the centre of a sub-critical reactor core is bombarded vertically by the high-energy protons from an accelerator. The main functions of the control system for the target are to monitor and control thermal hydraulic, neutron flux, and accelerator-target interface. The first function is to control the components in the primary and secondary loops, such as pumps, heat exchangers, valves, sensors, etc. For the commissioning measurements of the accelerator, the second function is to monitor the neutrons from the spallation target. The three-layer architecture has been used in the control system. In the middle network layer, in order to increase the network reliability, the redundant Ethernet based on Ethernet ring protection protocol has been considered. In the bottom equipment layer, the equipment controls for the above-mentioned functions have been designed. Finally, because the main objective of the target is to integrate the accelerator and the reactor into one system, the integration of accelerator's control system and the reactor's instrumentation and controls into the target's control system has been mentioned.

In this paper, we report the design of the control system for the spallation target in China initiative accelerator driven sub-critical (ADS) system, where a heavy-metal target located vertically at the centre of a sub-critical reactor core is bombarded vertically by the high-energy protons from an accelerator. The main functions of the control system for the target are to monitor and control thermal hydraulic, neutron flux, and accelerator-target interface. The first function is to control the components in the primary and secondary loops, such as pumps, heat exchangers, valves, sensors, etc. For the commissioning measurements of the accelerator, the second function is to monitor the neutrons from the spallation target.
