Description

A suite of experiments measuring target-spin observables in electron-nucleon scattering (dubbed Run Group C) was recently executed in Jefferson Lab. These experiments involved the scattering of an 11 GeV electron beam from longitudinally polarized nucleon targets located within the CLAS12 spectrometer in Hall B. The dynamically polarized target used in these experiments was designed and constructed exclusively for operation inside the CLAS12 and further optimized for the requirements of Run Group C. We will report on the operational experience with the target, the benchmarks achieved using various polarizable and unpolarized materials as well as the complete target setup, and the comprehensive target polarization analysis.
