| Abstract: | The emittance of heavy ion beams (Ar+, Si+ and Bi+) extracted from Nielsen source was measured. The measurements of emittance with slit-probe method were performed on a test bench at different positions of the beam line (in front of and behind the annalyzing magnet).The measuring errors of emittance were corrected with different focusing voltages of einzellens.The experimental results showed that the emittances were different with the gap of the extraction, the shape of the plasma boundary and the increase of the ion mass and intensity of ion beams. |
