View of the first bending magnet in the beam-line from the Synchro-Cyclotron (SC) to the ISOLDE laboratory.

The magnet steers the beam down through a hole cut in the floor of the SC hall, to the underground tunnel leading to the target room. The magnet frame was specially designed in the SC drawing offices so that the magnet can be rotated around the axis of the beam. The short shutdown of the SC, when the major components of the beam-line where installed, finished on 14 April. Before the end of the month, beam had been taken as far as the target. Intensities of 3 X 10n protons per second have been achieved, with a beam cross-section (containing 90 % of the protons) of 3 cm diameter. Tests were carried out to ensure the adequacy of the installed shielding and the results are now being analysed.
