Helical magnetic fields play an important role in star formation and stellar wind shaping. In recent years, there have been many experiments using pure poloidal or toroidal fields to confine hot plasma species that have successfully reproduced jets and instability patterns similar to those in the universe, but the role of helical magnetic structures is rarely explored due to the complexity of their generation. However, certain processes like cloud angular momentum extraction will only manifest in helical field configurations. In this article, we propose and numerically illustrate a method that can generate helical magnetic structures inside the plasma by merging a self-generated toroidal field and an externally applied poloidal field. The resulting helical field is dynamically important regarding pressure, adjustable in strength and pitch angle, and consistent with the actual astrophysical outflow in terms of boundary conditions. This method shows how to integrate a helical field structure into laser-plasma experiments, and it provides a framework for future studies on stellar outflow interaction with their embedded helical fields.

螺旋磁场在恒星形成和恒星风形成中起着重要作用。近年来，已经有许多使用纯极向或环形场来限制热等离子体物种的实验，成功再现了类似于宇宙中的射流和不稳定性模式，但由于螺旋磁结构的复杂性，很少探索螺旋磁结构的作用。他们这一代。然而，某些过程，如云角动量提取，只会出现在螺旋场配置中。在本文中，我们提出并数值说明了一种方法，该方法可以通过合并自生环形场和外部施加的极向场来在等离子体内部产生螺旋磁结构。由此产生的螺旋场在压力方面具有重要的动态意义，可调节强度和俯仰角，并且在边界条件方面与实际的天体物理流出一致。该方法展示了如何将螺旋场结构整合到激光等离子体实验中，并为未来研究恒星外流与其嵌入的螺旋场相互作用提供了框架。
