The RF system comprises two separated resonators driven by independent amplifiers to allow for the phase and amplitude modulation technique to be applied for beam intensity modulation. The cyclotron works on 4th harmonic with Dee’s voltage 80kV frequency 37MHz. According to the physical requirements of the superconducting cyclotron, the cavity is designed to be vertical 1/2 wavelength line structure, the geometry structure of DEE is optimized repeatedly for the ideal voltage distribution .In order to compensation frequency drift caused by the thermal and mechanical deformation, the fine-tuning loop has been designed to meet the dynamically tuned requirements PB - JACoW Publishing CP - Geneva, Switzerland SP - 37 EP - 39 KW - cyclotron KW - cavity KW - simulation KW - injection KW - extraction DA - 2019/11 PY - 2019 SN - 978-3-95450-203-5 DO - doi:10.18429/JACoW-HIAT2018-MOPB03 UR - http://jacow.org/hiat2018/papers/mopb03.pdf ER -
