The Neutron Structure Function from BoNuS

摘要

The BoNuS experiment at Jefferson Lab's Hall B measured the structure of the neutron via electron scattering off a deuterium gas target. By augmenting the CLAS detector with a novel radial time projection chamber featuring gas electron multipliers, very low momentum recoiling spectator protons were detected at very backward angles. The selection of these protons provides a tag for scattering on quasi-free neutrons.
