Booster Repetition Rate Limits
•Presently, the Booster is limited to an average rep. Rate of 2.5 Hz, which would only yield a small fraction of the desired MiniBooNE intensity. The primary limitation is the pulsed extraction septum magnet (MP02).
•A new power supply will go in in the next few weeks, which will raise this rate to 4.5 Hz, which would give about half the nominal MiniBooNE rate.
•A new magnet will go in during the January shutdown which will allow the Booster to go to 7.5 Hz – enough for MiniBooNE or NUMI.
•In order to run both MiniBooNE and NUMI, we need
–More cables for the extraction septum.
–Cooling for the RF cavities (or new RF cavities)
–A new “bump” magnet, which steers beam out during injection.
