	Funding: This work was supported by National Research Foundation of Korea (NRF) Grant No. 20110018946, and also by World Class University project of the NRF. A carbon beam was extracted and measured in the injection beam line built for an accelerator mass spectrometer (AMS) based on a cyclotron. The cyclotron AMS has been designed to realize a compact AMS having a mass resolving power of around 4000 for a negative 14C beam. The beam line is a prototype to ensure the capability to match the beam phase space with the acceptance of the cyclotron. The injection beam line consists of an ion source, Einzel lens, rf buncher, 90 degree dipole magnet and a beam diagnostic box with a slit system. The ion source with a hot filament is a commercial product, and all other elements were designed and built in house. Some measurement results of the beam line components as well as beam emittance will be presented.
