HIRFL-CSR global control network is used to define the correct location and orientation of accclcrator subsystems(i.e.CSRm,CSRe and Injection line)to each other.Each subsystem has its own control network,named the local control network.According to the local control network,thc components of each subsystem can be mounted to an ideal position.The original point of HIRFL-CSR global control network is on the mechanical
