我们正在开发紧凑型X波段直线加速器X射线源，用于无损评估和医学。首先，我们利用950keV 9.4 GHz X波段直线加速器研制了便携式X射线系统，实现了现场检测。我们使用一个低功率(250kW)的磁控管作为射频源，以保证整个系统的紧凑性。由于射频功率源很小，结构中存储的能量也很小，所以我们面临着束流加载和电流/射频功率振荡的问题。我们正在通过电路模型来分析问题。我们计划将该系统用于石化总厂金属管道的腐蚀检测。通过采用侧面耦合腔设计来避免振荡，我们研制了6 MeV X波段(9.3 GHz)直线加速器，用于肿瘤治疗的精确动态跟踪。此外，我们正在制造3.95 MeV(9.3 GHz)X波段柔性波导直线加速器X射线源，用于现场桥梁检测。给出了最新的结果和情况。
We are developing compact X-band linac X-ray sources for nondestructive evaluation and medicine. First, we develop a portable X-ray system by a 950keV 9.4GHz X-band linac to realize on-site inspection. We use a low power (250kW) magnetron as an RF source for compactness of the whole system. Since the RF power source is quite small and the stored energy in the structure is also small, we faced the problem of beam loading and current/RF-power oscillation. We are analyzing the problem by the circuit model. We plan to use this system for erosion inspection of metal pipes of petrochemical complex. By adopting a side-coupling cavity design to avoid the oscillation, we have developed 6MeV X-band (9.3GHz) linac for pinpoint dynamic tracking cancer therapy. Furthermore, we are manufacturing 3.95MeV X-band (9.3GHz) linac X-ray source with flexible waveguides for on-site bridge inspection. Updated results and situations are presented.
