We have studied the extraction and transport of a low-energy ion beam between an Electron Cyclotron Resonance (ECR) Ion Source and the analyzing magnet. This first part of the transport line is particularly sensitive to emittance blowup caused by ion-optical aberrations and non-paraxiality of the beam. This can be prevented by an appropriate focussing element between ion source and analyzing magnet. We present the results of beam transport simulations for different focussing elements including an einzel lens, solenoid and quadrupole element. These calculations, verified by measurements, lead to a design of an optimal, low-energy beam transport line for ion beams with large beam divergences.
