| 摘 要： | 通过优化设计法拉第筒的响应电阻和分布电感，在“TPG700”平台上对无箔二极管阴极发射的环形电子束束流进行轴向测试。结果表明，无波二极管工作在低磁场(<1 T)条件下，在二极管电压较低时，优化后的法拉第筒测试获得的电子束束流前沿较慢，随着二极管电压的升高，电子束束流前沿明显变快；在强磁场(>2 T)条件下，法拉第筒测试结果与罗果夫斯基线圈测试结果一致。该结果表明，相比于罗果夫斯基线圈，法拉第筒更能准确地测试出无箔二极管的前向电子束束流。

| Abstract: | The foil-less diode electric beams is measured by using Faraday cup on the TPG700 generator platform. The results show when the diode voltage is low, the diode electric beams rising edge is slower. The diode electric beams rising edge is getting faster as the diode voltage increases. The diode current magnitude by the Rogowski coil measurement is in accordance with that by the Faraday cup measurement for intense magnetic field. When magnetic field is smaller than 1 T, the diode current magnitude by the Rogowski coil measurement is obviously bigger than that by the Faraday cup measurement. The Faraday cup can give accurate measurement on the front electric beams of foil-less diode. |
