A feedback microprocessor for hadron colliders
- Fermi National Accelerator Laboratory, Batavia, Illinois 60510 (United States)
A feedback microprocessor has been built for the Tevatron. It has been constructed to be applicable to hadron colliders in general. Its inputs are realtime accelerator measurements, data describing the state of the Tevatron, and ramp tables. The microprocessor software includes a finite-state machine. Each state corresponds to a specific Tevatron operation and has a state-specific Tevatron model. Transitions between states are initiated by the global Tevatron clock. Each state includes a cyclic routine, which is called periodically and where all calculations are performed. The output corrections are inserted onto a fast Tevatron-wide link from which the power supplies will read the real time corrections. We also store all of the input data and output corrections in a set of buffers that can easily be retrieved for diagnostic analysis. In this paper we describe this device and its use to control the Tevatron tunes as well as other possible applications. [copyright] 1995 [ital American] [ital Institute] [ital of] [ital Physics]
