Super Bigbite Spectrometer

The Super Bigbite spectrometer (SBS) has operated successfully in several recent experiments. The magnetic structure of the SBS is based on a large warm coil dipole. The key element, which allows a large solid angle (up to 70 msr) at a small scattering angle, is a cut in the yoke for the beam line. In 2007 the first SBS proposal to measure the proton electric form factor at momentum transfer up to 12 GeV^2 was approved, and later a large physics program followed. We will present the details of the SBS configuration and the physics concepts behind most of the approved experiments. In addition to the high momentum transfer and high-z experiments, there is important physics of the electron scattering from the polarized NH3/ND3 and He-3 targets which benefits from a large acceptance and momentum bite of the SBS.
