先前已经提出，在两种不同Z材料之间的界面处的电阻率梯度可以允许由于磁场的电阻自生成的增强增长而引导在固体密度靶中传播的激光生成的快速电子束，并且这可以在椭圆形靶中采用以产生用于传播通过均匀材料的更准直的束。在本文中，我们表明，一个小角度的圆锥形元件也可能有很高的效率，在产生准直流。虽然锥形元件不具有椭圆形配置的几何聚焦特性，但是锥形元件将倾向于通过减小快速电子在每次连续反弹时的传播角来减小快速电子的角展度
Previously it has been suggested that the resistivity gradient at the interface between two different Z materials may allow one to guide a laser-generated fast electron beam propagating in a solid density target due to the enhanced growth of resistive self-generation of magnetic field and that this might be employed in an ellipsoidal target to produce a more collimated beam for propagation through homogeneous material. In this paper we show that a low-angle conical element may also have high efficacy in producing a collimated flow. Although the conical element does not have the geometric focussing properties of the ellipsoidal configuration, the conical element will tend to reduce the angular spread of the fast electrons through reducing their propagation angle on each successive bounce
