基于Greenwood的一项专利，结合UM/L-3相对论磁控管，利用粒子模拟程序ICEPIC，提出了一种紧凑的轴向π模提取方案。利用格林伍德的提取技术的情况下，使用传统的径向波导功率提取进行了比较。所有模拟轴向情况下的平均提取功率值均在径向情况的+/-6.5%范围内。利用85 °和90°扇形波导的情况下，发现有效率高达10个百分点高于径向的情况下。发现最佳性能的情况是使用一组三个轴向定向的90 °扇形波导，在上游侧短路，短路位于距磁控管孔中心15 cm处。
A compact axial π-mode extraction scheme, which is based on a patent by Greenwood, is demonstrated in conjunction with the UM/L-3 relativistic magnetron using the particle-in-cell code ICEPIC. Cases utilizing Greenwood's extraction technique were compared with power extraction using traditional radial waveguides. Average extracted power values in all simulated axial cases were found to be within +/-6.5% of the radial cases. Cases utilizing 85 ° and 90° sector waveguides were found to have efficiencies up to ten percentage points higher than the radial case. The best performing case was found to use a set of three axially oriented 90 ° sector waveguides, shorted on the upstream side, with the short located 15 cm from the center of the magnetron apertures.
