TUPAF075 | Design Status of the LBNF/DUNE Beamline | 902 |
|
||
Funding: DOE, contract No. DE-AC02-07CH11359 The Long Baseline Neutrino Facility (LBNF) will utilize a beamline located at Fermilab to provide and aim a wide band beam of neutrinos of sufficient intensity and appropriate energy toward DUNE detectors, placed 4850 feet underground at SURF in South Dakota, about 1,300 km away. The primary proton beam (60-120 GeV) will be extracted from the MI-10 section of Fermilab's Main Injector. Neutrinos are produced after the protons hit a four-interaction length solid target and produce mesons which are subsequently focused by a set of three magnetic horns into a 194 m long helium filled decay pipe where they decay into muons and neutrinos. The parameters of the facility were determined taking into account the physics goals, spatial and radiological constraints, extensive simulations and the experience gained by operating the NuMI facility at Fermilab. The Beamline facility is designed for initial operation at a proton-beam power of 1.2 MW, with the capability to support an upgrade to about 2.4 MW. LBNF/DUNE obtained CD-1 approval in November 2015 and CD-3a approval in September 2016. We discuss here the Beamline design status and the associated challenges. |

WEPML011 | Garnet Ring Measurements for the Fermilab Booster 2nd Harmonic Cavity | 2700 |
|
||
A perpendicularly biased tuneable 2nd harmonic cavity is being constructed for use in the Fermilab Booster. The cavity's tuner uses National Magnetics AL800 garnet as the tuning media. For quality control, the magnetic properties of the material and the uniformity of the properties within the tuner must be assessed. We describe two tests which are performed on the rings and on their corresponding witness samples. | ||

WEPML012 | Progress on the Construction of the Perpendicularly Biased 2nd Harmonic Cavity for the Fermilab Booster | 2703 |
|
||
A perpendicularly biased tuneable 2nd harmonic cavity, designed for the Fermilab Booster, is being assembled for testing this summer (2018). The cavity will work at twice the frequency of the fundamental cavities, and will be on only during the injection and transition (or extraction) periods. The main purpose of adding this cavity is to improve beam capture and reduce losses as required by Fermilab's Proton Improvement Plan (PIP). After three years of testing and optimization, the cavity design has now been finalized and all constituent parts have been received. We report on the cavity final design and on the status of the construction. | ||
