The G0 experiment measures the parity-violating asymmetries in elastic electron-proton and quasi-elastic electron-deuteron scattering over the momentum transfers 0.12 {<=} Q2 {<=} 1.0 GeV2. These asymmetries are sensitive to the strange-quark contribution to the charge and magnetization distributions of the proton. The experiment is conducted at Jefferson Laboratory using a toroidal spectrometer designed to detect forward scattered recoil protons and backward scattered elastic and quasi-elastic electrons. The forward angle experiment was completed in 2004, and the backward angle phase of the experiment is currently taking place.
