[en] Losses in the low-energy beam transport line from the KVI-AECRIS to the AGOR cyclotron are estimated to be around 50 %. Numerical simulations of beam extraction and transport have been performed up to the image plane of the analyzing magnet. The simulations show overall good agreement with measurements of beam profiles and emittances. It was found that the beam losses are caused by a too small gap of the analyzing magnet. This magnet also suffers from large second-order aberrations causing a significant increase of the effective beam emittance in both horizontal and vertical directions. We show that by increasing the magnet gap and suitably modifying the pole surfaces the beam losses can be suppressed and the second order aberrations significantly reduced. This results in a substantially lower effective emittance of the transported beam. The paper is followed by the slides of the presentation. (authors)
