The Neutron Magnetic Form Factor Experiment on the SuperBigBite Spectrometer at Jefferson Lab

The Neutron Magnetic Form Factor, Gⁿ_M, gives insight into the magnetic moment distribution of the neutron. Experiment E12-09-019 in Hall A at Jefferson Lab took data to measure Gⁿ_M at high Q² up to Q² = 13.6 (GeV/c)² on the newly built SuperBigBite Spectrometer (SBS) apparatus. Electrons from quasi-elastic electron scattering on a deuterium target are measured in coincidence with the struck nucleon in a large hadron calorimeter. Simultaneous measurements of protons and neutrons allows utilization of a ratio method, causing many systematic uncertainties to cancel. The results from this experiment will significantly extend the range into large Q² for the Gⁿ_M world data. The experiment was conducted from Fall 2021 through Spring 2022 and was the commissioning experiment for the detectors. Calibrations of these new detectors constitutes a significant portion of the data analysis. The heavy gas Cherenkov detector (GRINCH) consists of 510 1-inch photomultipier tubes and C₄F₈ heavy gas to aid in pion and electron identification in the high background environment. In this talk, I will give an overview of the Gⁿ_M experiment, show calibrations for GRINCH, and report my analysis progress towards physics results for my assigned kinematic settings.
