  The Fermilab Booster and Main Injector synchrotrons produce high-rate proton beams for neutrino and antiproton production. Operation of these machines at high beam power has required novel approaches to managing beam loss during acceleration and at extraction. Routinely, the beam loss in the Booster limits it throughput, instead of any physical limitation. With pending intensity upgrades the same may also become true of the Main Injector. Future advances in beam power require a fully complementary reduction of oncontrolled losses.

  The Fermilab Main Injector currently accelerates 300 kW of 120 GeV protons for antiproton and neutrino production. We report on searches for the formation of an electron cloud within the Main Injector, and possible associated proton beam instabilities. Current capabilities and instrumentation upgrades will be discussed. These studies are performed with the anticipation that future plans could lead to a fourfold increase of the proton charge in the Main Injector.

  Slip stacking for pbar production has been operational since December 2004 and increased the beam intensity on pbar target more than 60%. We plan to use slip stacking for NuMI neutrino experiment for effectively increasing intensity to NuMI target by about a factor two in a 2.2 sec MI cycle. In parallel with slip stacking, we plan to study fast momentum stacking using barrier buckets. One barrier rf system has been installed and tested, and second system is being installed during the current shutdown.
