摘要

自磁夹脚二极管被认为是未来高压(10MV)闪光射线照相系统的可能来源。英国原子武器机构(AWE)奥尔德马斯顿和美国桑迪亚国家实验室(SNL)之前的研究都研究了二极管产生的时间集成剂量和源直径。这里介绍的是对震源直径动态时程的研究结果。在AWE和SNL进行了实验研究,用纳秒门控和条纹相机将源图像投影到快速衰减闪烁体上。比较了二维和三维电磁粒子在细胞编码中的实验测量结果。

Studies into the Time Resolved Source Diameter of a Self Magnetic Pinch Radiographic Diode
The self magnetic pinch diode is being considered as a possible source for future high voltage (10MV) flash radiographic systems being developed. Previous studies at both the Atomic Weapons Establishment (AWE) Aldermaston in the UK and Sandia National Labs (SNL) in the US have investigated the time integrated dose and source diameter produced by the diode. Presented here are results from investigations into the dynamic time history of the source diameter. Experimental investigations have been carried out at both AWE and SNL with the image of the source projected onto fast decay scintilators viewed by nanosecond gating and streak cameras. Experimental measurements are compared with results from 2D and 3D electromagnetic particle in cell codes.
