This album shows the alignment of the magnetic channel in the northern branch of the slow ejected proton beam-line, e₃ , in progress. There are 10 deflecting units in this section of e₃. In the background, a large bending magnet can be seen behind which the targets to provide the secondary particle beams will be placed. The beam-line is surrounded by the usual sheath of iron and concrete shielding to limit the radiation level in the rest of the East Hall.
