1 GANIL - Grand Accélérateur National d'Ions Lourds

We routinely accelerate up to micro-amperes of ions at energies ranging from 25 to 95 MeV / A. Already at these levels, space charge (S.C) problems drastically affect the bunching efficiency between the ECR external ion-source and our Co compact injector. Moreover in the "2.5" version of GANIL we expect currents above 50 e\l A (Ar+6 for instance) and S.C effects will be of prime importance during acceleration in the injector and even in our first SSC. We present our computer codes and our first results.
