Accelerator complex in the Intensity Frontier

  • Increase the Booster Beam Power by a factor of 2.2

by running the Booster at 15 Hz

  • Proton improvement plan provides the necessary

upgrades assuring high machine availability and low residual activation.

  • Increase the MI beam power by 1.7 to 700 KW by

utilizing the Recycler as a proton accumulator with stacking.

  • ANU Plan provides the Recycler upgrades
  • Need to commission slip stacking in the Recycler.
  • Reconfigure the pbar source into a muon campus

for mu2e/g-2.

  • Series of AIPs/GPPs provide the necessary modifications

required for both experiments.

increased by 9% (per bunch intensity remains the same).

  • No Instability Issues are

anticipated.

  • Loss control is the major

Issue (Power loss is increased by 80%).

Conclusions

  • With the completion of the current shutdown the

Accelerator Complex enters the Intensity Frontier.

  • The Proton Improvement Plan will enable the

Booster to reliably run at 15 Hz.

  • RF cavity refurbishment is the critical path
  • The ANU Upgrades will enable Main Injector to

provide 700 KW of beam power from 80-120 GeV.

  • Plans are in place for transforming the pbar

source into a muon campus for g-2/mu2e.
