| 摘 要： | 3.5 MeV 注入器是“神龙一号”直线感应加速器的束源，在注入器束流调试中，首先通过数值模拟方法，初步确定束流过聚焦和聚焦不足两种极端情况下引出线圈输运磁场峰值的变化范围；然后以注入器出口束流波形为参考，通过实验调试找到了这两种情况下引出线圈输运磁场峰值的实际配置；再通过测量束流的剖面或发射度，在这两种配置中选定一个折中的引出线圈磁场配置，并最终确定了注入器输运磁场的总体配置。经过调试完成后的注入器束流为3.6 MeV，流强为2.8 kA，归一化边发射度为1 040 mm·mrad，达到了预期的指标。

| Abstract: | The 3.5 MeV foilless injector is the electron source of dragon-Ⅰ linear induction accelerator(LIA). In beam tuning, the variety range of magnetic field is approximately determined by simulation. Based on the beam current waveforms at injector exit, the magnetic field profile of diode is decided by experiments. By measureing some beam parameters, the layout of magnetic field for the whole injector is obtained. The tuning experimental results show that this injector has achieved prospective guide line with an output beam energy of 3.5 MeV, a beam current of 2.8 kA and a normalized emittance of 1 040 mm·mrad. |
