Abstract :
In ILSE (Induction Linac Systems Experiment), sixteen intense parallel ion beams are to be transversely combined into four by dispersionless double bends. Emittance growth due to electrostatic energy redistribution and to the geometry is evaluated. Most bending elements are electric, and alternate with AG electrostatic quadrupoles similar to those upstream. The final elements are magnetic, combining focusing and `unbending´. Electrode shapes and pulsed-current arrays (with very small clearances), as well as mechanical and electric features of the combiner, are described
