  FAIR - the international facility for antiproton and ion research – located at GSI in Darmstadt, Germany is one of the largest research projects worldwide. It will provide an antiproton production rate of 7·1010 cooled pbars per hour, which is equivalent to a primary proton beam current of 2·1016 protons per hour. A high intensity proton linac (p-linac) will be built, with an operating rf-frequency of 325 MHz to accelerate a 70 mA proton beam up to 70 MeV, using conducting crossed-bar H-cavities. The repetition rate is 4 Hz with an ion beam pulse length of 36 μs[1]. Developed within a joint French-German collaboration - GSI/CEA-SACLAY/IAP – the compact proton linac will be injected by a microwave ion source and a low energy beam transport (LEBT). The 2.45 GHz ion source allows high brightness ion beams at an energy of 95 keV and will deliver a proton beam current of 100 mA at the entrance of the RFQ (Radio Frequency Quadrupole) within an emittance of 0.3π mm mrad (rms). To check on these parameters computer simulations with TraceWin, IGUN and IBSIMU of the ion extraction and LEBT (Low Energy Beam Transport) are performed.
