The $Q_{\mathrm{weak}}$ Experiment: Measurement of the Elastic Parity-Violating e-p Asymmetry at Low Q$^{2}$

Q-weak part 1. The $Q_{\mathrm{weak}}$ experiment at Jefferson laboratory has measured the parity-violating asymmetry in e-p elastic scattering at Q$^{2} =$ 0.025 (GeV/c)$^{2}$, employing longitudinally polarized electrons incident on a 34.5 cm long liquid hydrogen target. The measurement was performed using an integrating mode apparatus with a set of eight quartz Cerenkov detectors placed radially along the beam axis. The resulting measured asymmetry is then corrected for various effects, including false asymmetries generated by helicity-correlated beam properties, backgrounds from aluminum target windows and the beamline, and the beam polarization. The results of the experiment's commissioning run will be reported, which consist of approximately 1/25$^{\mathrm{th}}$ of the total data collected during the full measurement. This talk will focus on the $Q_{\mathrm{weak}}$ apparatus and the analysis to determine the asymmetry. A value of the physics asymmetry from the experiment's commissioning run will be presented.
