The original LEBT had a focal point before mass separation which emphasized the space charge induced problems in the beam transport at low energies. The new LEBT injects a diverging beam into the dipole magnet. The first double focusing dipole magnet focuses the beam into a focal point is at the collimation plane. The first solenoid SOLJ1 is used for fine tuning the beam divergence together with the electrostatic lenses.
