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. 4 I. Kourbanis Fermilab Users Meeting June 12-13 2013
