A new beam line to allow parasitic experiments in two separate experimental halls has been installed. The total length of the beam line is about 80 m. Two achromatic 90° deflecting systems have been incorporated. For the beam delivered to the second experiment, the beam diameter was 2 mm and the emittance was 1 mm mrad. The duty factor was reduced to an average of 50% from 80%. This decrease was satisfactorily recovered using a deflector system synchronized with the beam pulse. The tagged photon beam, and experimental conditions were significantly improved when the transported beam was used. Successful parasitic experiments involving electron scattering and tagged photon experiments have now been demonstrated.
