Enhancing Particle Acceleration in Booster with Permanent Magnet Accumulator Ring

A permanent magnet accumulator ring could revolutionize the Booster facility, benefiting PIP-II/DUNE programs and advancing FNAL toward a large-scale DS program. By integrating the new 1 GeV line within the existing Booster to BNB enclosure, costs and timelines are significantly reduced. The proposal includes the design of an 800 MeV line for PIP-II injection, with the new accumulator ring redirecting PIP-II linac beam to the Booster for DUNE operations. This innovative approach maximizes efficiency and facilitates DS operations at FNAL.

Presentation Transcript

1. Booster Accumulator Ring LOI

2. Overview A permanent magnet accumulator ring could be built in the Booster enclosure that could greatly benefit PIP II/DUNE program and set FNAL on the path to a large DS program. The existing Booster to BNB enclosure will be contain the new 1 GeV line. Cost and time for this approach is greatly reduced due to synergy to PIP II and present BNB complex. A new 800 MeV line is being designed for the PIP II to Booster Injection. A new accumulator would instead receive the PIP-II linac beam and transfer it to the Booster for DUNE operations. With the rest of the Linac pulses being used for delivery to the BAR for DS operations.
