Proton Beam Intensity Upgrades for the Neutrino Program at Fermilab

TL;DR

Fermilab is upgrading its accelerator complex with new beam injection schemes and power enhancements to significantly boost neutrino research capabilities, including the implementation of the innovative 'early injection scheme' for the Booster.

Contribution

The paper introduces and reports on the operational experience of the novel 'early injection scheme' that increases beam intensity and reduces beam loss in Fermilab's Booster.

Findings

Successful commissioning of the 'early injection scheme'

Increased Booster beam intensity beyond design goals

Reduced beam emittance and beam loss

Abstract

Fermilab is committed to upgrading its accelerator complex towards the intensity frontier to pursue HEP research in the neutrino sector and beyond. The upgrade has two steps: 1) the Proton Improvement Plan (PIP), which is underway, has its primary goal to start providing 700 kW beam power on NOvA target by the end of 2017 and 2) the foreseen PIP-II will replace the existing LINAC, a 400 MeV injector to the Booster, by an 800 MeV superconducting LINAC by the middle of next decade, with output beam intensity from the Booster increased significantly and the beam power on the NOvA target increased to <1.2 MW. In any case, the Fermilab Booster is going to play a very significant role for the next two decades. In this context, we have recently developed and commissioned an innovative beam injection scheme for the Booster called "early injection scheme." This scheme is already in operation and has a potential to increase the Booster beam intensity from the PIP design goal by a considerable amount with a reduced beam emittance and beam loss. In this paper, we will present results from our experience from the new scheme in operation, current status and future plans.
