The planned SoLID detector is a large acceptance forward scattering spectrometer with full azimuthal angular coverage capable of handling high luminosities (1037 – 1039/cm2/s) with a variety of polarized and unpolarized targets. The detector will exploit the full potential of the JLab 12 GeV upgrade with programs in 3D imaging of the nucleon, beyond standard-model searches and exploration of gluonic forces.
