A-1. Performance Review of Space-Charge-Limited Facilities A

Speaker

Robert Ainsworth (Fermi National Accelerator Laboratory)

Description

The Fermilab Accelerator Complex currently delivers the world’s most powerful neutrino beam, powered by a 1 MW, 120 GeV proton beam from the Main Injector. The forthcoming PIP-II upgrade will increase beam delivery demands, requiring the Main Injector and Recycler to stack and accelerate roughly 50% more beam with only limited upgrades to the existing complex.
This talk will review recent high-intensity performance achievements and identify the key limitations that must be addressed to support future operation. Particular focus will be placed on space-charge-driven intensity limits, beam loss and operational constraints in the Recycler and Main Injector.
