Abstract

Results of experimental studies of the spatial and temporal characteristics of the hard X-rays generated by high-current electron beams in X-pinch experiments on the XP (Cornell University) and BIN (LPI RAS) pulsed power generators are presented. Some issues concerning high-current electron beam transport from the X pinch to the diagnostic system and measurements of the beam current by Faraday cups with different geometries are discussed. Generation of electron beams is an unavoidable property of X-pinches and other pulsed-power-driven pinches of different geometry. Results of computer simulation of electron beam propagation from X-pinch to Faraday cup give the limits of measured current for beams having different energy spread. We emphasize the partially neutralized nature of the beam propagating from the X-pinch to a diagnostic system. Different schemes for beam space-charge neutralization are discussed. Longitudinal neutralization is thought to be the most important method because it enables transport of beams with close to the Alfven current. Experimental and computer simulation results on electron beam generation are compared.

硬x射线和高电流电子束
本文介绍了在美国康奈尔大学XP和美国LPI RAS脉冲功率发生器上进行的大电流电子束产生的硬x射线的时空特性实验研究结果。讨论了大电流电子束从X缩点到诊断系统的输运以及不同几何形状的法拉第杯测量电子束电流的一些问题。电子束的产生是x缩进和其他不同几何形状的脉冲功率驱动缩进不可避免的特性。计算机模拟了电子束从X-pinch到法拉第杯的传输过程,给出了不同能量扩散的电子束的电流极限。我们强调了从x -掐向诊断系统传播的光束的部分中和性质。讨论了不同的束流空间电荷中和方案。纵向中和被认为是最重要的方法,因为它可以使光束以接近阿尔芬电流的方式传输。对电子束产生的实验结果和计算机模拟结果进行了比较。
