The feasibility of a new slow extraction system for LEIR based on the third integer resonance was studied with two possible resonance driving mechanisms: quadrupole-driven extraction and RF-knockout extraction. The extraction of fully stripped carbon ions (20-440 MeV/u kinetic energies) has been studied in detail. The requirement to keep the present performance of the machine for physics experiments imposes tight space constraints for the upgrade. The extraction scheme and the hardware requirements are described in this paper.
