Neutron Structure Functions Measured with Spectator Tagging
… at Jefferson Lab addressed this problem by tagging spectator protons in coincidence with inelastic electron scattering from deuterium. A novel compact radial time projection chamber was built to detect low-momentum, backward moving protons, ensuring that the scattering took place on a …

Exclusive π- Electro-Production From the Neutron in the Resonance Region
… neutron target. To overcome this limitation, the spectator tagging technique was used in one of the CEBAF Large Acceptance Spectrometer (CLAS) collaboration experiments, <em>Barely off-shell Nuclear Structure (BoNuS)</em>, in Hall-B at Jefferson Lab. We have constructed a radial time projection …

Spectator Proton Detection and Reconstruction in Deep Inelastic <i>D(E,EP<sub>S</sub>)</i> Scattering
… the new RTPC was used to detect low- momentum spectator protons. Protons follow a curved path in the 5 Tesla solenoid that is part of CLAS12, ionizing the He-CO2 gas in an annular drift region surrounding the target. These ionization electrons are radially drifted outwards, amplified using …

Electron Scattering From a High Momentum Neutron in Deuterium
… be inferred if we assume that the proton was a spectator to the reaction. This method, known as spectator tagging, was used to study the electron scattering from high-momentum neutrons in deuterium. The data were taken with a 5.765 GeV polarized electron beam on a deuterium target in Jefferson …

Test of New Readout Electronics for the BONuS12 Experiment
… a RTPC capable of detecting the low-momentum spectator protons near the target. Events of electrons scattering on almost free neutrons are selected by constraining the spectator protons to very low momenta and very backward scattering angles. In 2005, BONuS successfully measured the neutron …
