The prototype message broadcast system for the Superconducting Super Collider
K. Low, Robert Skegg · IEEE Transactions on Nuclear Science · 1991
A prototype unified message broadcast system to handle the sitewide distribution of all control system messages for the Superconducting Super Collider (SSC) is presented. The messages are assembled in the control room area and encapsulated for transmission via a general fiber-optic link system to devices distributed throughout 70 mi of tunnels. An embedded timing signal is used by the distribution system to ensure that messages arrive at all devices simultaneously. Devices receive messages using a special receiver subsystem. A simple version of this system is to be used in the Accelerator Systems String Test (ASST) at the SSC site in 1991.>
