    "abstract": "This paper presents the requirements and design of a Timing Synchronization\nSystem (TSS) for the Continuous Electron Beam Accelerator Facility (CEBAF)\ncontrol system at Thomas Jefferson National Accelerator Facility. A clock\nmodule has been designed which resides in a VME crate. The clock module can be\na communications master or a slave depending on its configuration, which is\nsoftware and jumper selectable. As a master, the clock module sends out\nmessages in response to an external synchronization signal over a serial fiber\noptic line. As a slave, it receives the messages and interrupts an associated\ncomputer in its VME crate. The application that motivated the development of\nthe TSS, the Accelerator 30 Hz Measurement System, will be described.\nOperational experience with the TSS will also be discussed.",
