Phase synchronization between Booster extraction and Recycler injection has been done with the phase lock loop at Booster extraction. The phase Lock Loop control rf phase by changing radial position at extraction and it causes ± one bucket error, not phase error at Recycler injection. By switching a mode of operation for the phase lock loop by measuring the extraction gap position, the jitter was eliminated. The beam loss at the Recycler injection was reduced by 20%. Beam studies and the phase lock system will be discussed in this paper.

The Booster Beam Notch is a beam gap needed to allow extraction kickers to reach full field strength for a single turn extraction scheme. The Notch is created at injection energy by kicking 3 out of the 84 bunches to a dedicated absorber. The kicker voltage, pulse length and geometry of the absorber must be optimized to minimize the beam loss due to the notch creation. Beam studies, simulation and implementation as well as the optimization and improvement of the notch system will be discussed in this paper.

Proton Improvement Plan-II (PIP-II) is Fermilab's plan for providing powerful, high-intensity proton beams to the laboratory's experiments. PIP II will include upgrades to the Booster, Recycler and Main Injector which will be required to accelerate 50% more beam as well as increasing the Booster repetition rate from 15 to 20 Hz. To accommodate the faster rate, the momentum separation of the slip stacking beams in the Recycler must increase which will result in in larger longitudinal emittance bunches in MI.
