论文摘要
在最近的一份评论论文中，广泛讨论了等离子体焦点中轴向（poloidal）磁场的存在及其在血浆焦点现象学中的重要性。多磁场是自发产生的瞬态3维磁场结构的一部分，加速离子，并使它们在反复穿越致密和温暖的血浆靶标的轨迹中移动。这是血浆焦点异常高的融合反应速率的起源，该反应速率自1960年代以来就已经知道，但最近才开始理解。现在进一步的进步取决于探索多磁场演化的全局方面。但是，轴向磁场测量标准技术涉及的众所周知的实验困难妨碍了此类研究工作。国际密集磁化等离子体的国际科学委员会在2020年4月24日的国际视频会议上发起了一项计划，以意识到这一僵局。
The existence of axial (poloidal) magnetic field in a plasma focus and its significance in plasma focus phenomenology has been extensively discussed in a recent review paper. The poloidal magnetic field is a part of the transient 3-dimensional magnetic field structures which arise spontaneously, accelerate ions and keep them moving in trajectories that repeatedly cross a dense and warm plasma target. This is the origin of the abnormally high fusion reaction rate of the plasma focus, which has been known since the 1960s but has begun to be understood quite recently. Further progress now depends on explorations of the global aspects of the evolution of poloidal magnetic field. However, well-known experimental difficulties involved in standard techniques of axial magnetic field measurement hamper such research efforts. Taking cognizance of this stalemate, the International Scientific Committee for Dense Magnetized Plasmas launched an initiative to address this state of affairs in an International Video Conference on 24th April 2020. This paper reports on the first experiments that resulted from that initiative
