Popis: As a part of the spin-physics program at the Jefferson Laboratory (TJNAF), a Moller polarimeter has been developed to measure the polarization of electron beam of energies between 0.8 and 6.0 GeV. A unique design of this polarimeter was developed using a set of three quadrupole magnets that provide an angular selection of the Moller electron pairs, a dipole magnet for their energy analysis, an a rotatable target system. The test procedure and commissioning of the polarimeter are presented. The results of beam polarization measurements in long-term physical experiments, the correlation for the three-beam accelerator mode and other effects are discussed.
