CYCIAE-50 is a compact H⁻ cyclotron with the proton beam energy of 30 MeV to 50 MeV and the beam current of 10 uA. A multi-cusp H⁻ ion source with the beam current of 3 mA will be used for this machine. The design on the injection and central region of CYCIAE-50 has been finished. The way of matching the beam from ion source to central region and the design of central region will be present in this paper. In addition, some significant problems in central region will be discussed, including radial alignment, axial focusing, longitudinal focusing and energy gain, etc. PB - JACoW Publishing CP - Geneva, Switzerland SP - 39 EP - 41 KW - injection KW - cyclotron KW - ion-source KW - MMI KW - solenoid DA - 2020/06 PY - 2020 SN - 978-3-95450-205-9 DO - doi:10.18429/JACoW-Cyclotrons2019-MOP007 UR - http://jacow.org/cyclotrons2019/papers/mop007.pdf ER -
