Abstract—

The generation of accelerated electron beams in a high-current Z-pinch formed by the implosion of wire cylindrical tungsten arrays on an Angara-5-1 facility is studied. The most intense characteristic and bremsstrahlung X-ray radiation of fast electrons is recorded from the central region of the pinch at the pin-ching stage. The transverse size of the radiation source in the characteristic tungsten radiation L_α is ~1.5‒1.8 mm, which is close to the transverse size of the radiation source in the soft X-ray emission (1‒1.5 mm). The current of accelerated electrons generated during the implosion of the wire array and the formation of a pinch is on the order of the Alfvén current (I_A). This result is consistent with the estimate of the current of accelerated electrons made from the measured characteristic radiation intensity L_α of tungsten under the assumption that the mean free path of fast electrons in a pinch is on the order of its length.

摘要-

研究了在安加拉（Angara）5-1设施上由圆柱形钨丝阵列爆裂形成的大电流Z形夹中加速电子束的产生。在收缩阶段，从收缩的中心区域记录了快速电子的最强特征和致辐射的X射线辐射。在特性钨辐射辐射源的横向尺寸大号_α是1.5-1.8〜毫米，这是接近在软X射线发射（1-1.5毫米）辐射源的横向尺寸。在线阵列内爆和形成收缩期间产生的加速电子的电流约为Alfvén电流（I _A）。此结果与从测量特性的辐射强度由加速的电子的电流的估计一致大号_α假设在捏快速电子的平均自由程长度的数量级下的钨。
