Introduction

Operational Modes

Functional Requirements

• all B2B and bunch to fixed target transfer at FAIR shall be supported
• both synchronization methods are available: Phase Shift and Frequency Beating
• the B2B transfer should be fulfilled within 10 ms and the precision better than 1 degree of the phase difference between bunch to bucket center
• the GMT shall be capable of providing timing messages for diagnostics and instrumentation
  • the 1st one can be used for trigger generation in coincidence upon transfer/extraction
  • the 2nd one is a follow-up message used to distribute diagnostic information on the transfer
• the B2B system has a close link to the MPS
  • the provides signals to inhibit extraction or triggers emergency extraction
  • the B2B system generates a trigger signal for kickers
  • a so-called Trigger Decision Module might serve as an interface between the B2B and the MPS system
