Performance of the BigBite Spectrometer during the Neutron Transversity Experiment in Hall-A

ORAL

Abstract

The Hall-A E06-010 collaboration at Jefferson Lab recently measured the neutron target single spin asymmetry(SSA) in the semi-inclusive deep inelastic $^{3}He^{\uparrow}(e,e'\pi^{+/-})X$ reactions with a transversely polarized $^3$He target. A high-resolution spectrometer was used to detect pions in coincidence with the scattered electrons detected in the large acceptance BigBite spectrometer. The kinematical range, $x = 0.13\sim 0.41$, at $Q^2=1.31\sim3.10~(\mathrm{GeV}/c)^2$, focuses on the valence quark region. SSA data from this experiment will provide important information to extract the quark transversity distribution in semi-inclusive deep inelastic scattering. In this talk the performance of the BigBite spectrometer and trigger setup will be presented along with the progress on the data analysis.
