Operational Modes

The following operational modes shall be supported by the B2B system.
Mode Description Source Target RF sync ext RF sync inj
KSE Evt-Kick-Start Ring N/A N N/A
B2E Bunch-2-Extration Ring (fixed) target, dump... Y N

Functional Requirements

The main functional requirements are defined in the technical concept as follows.

  • 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
