Cosmic Rays and the Interplanetary Magnetic Field

我们提出了一个广泛的研究计划，研究宇宙射线的加速、传输和太阳调制，太阳风中大规模和湍流磁场的本质，以及行星际等离子体这些子系统之间的相互作用。要求支助继续收集和分析来自格陵兰图勒和特拉华州纽瓦克中子监测站的数据。具体的科学目标包括：o详细分析和模拟第22太阳活动周期中由相对论性太阳粒子引起的地面水平增强；O综合分析宇宙射线日变化的高次谐波，从数据中提取局部行星际输运参数（包括磁螺旋度）的新信息；O对控制宇宙射线平均自由路径的因素的新想法进行详细的观测测试，包括湍流耗散、动力学和几何的影响；发展和实施新的观测方法来确定湍流几何形状，特别强调识别和测量可能的二维分量。

We propose a broad-based program of research into the acceleration, transport, and solar modulation of cosmic rays, the nature of large-scale and turbulent magnetic fields in the solar wind, and the interactions among these subsystems of the interplanetary plasma. Support is requested to continue the collection and analysis of data from neutron monitor stations in Thule, Greenland and Newark, Delaware. Specific scientific objectives include: o detailed analysis and modeling of the ground level enhancements caused by relativistic solar particles during Solar Cycle 22; o comprehensive analysis of the higher order harmonics of the cosmic ray diurnal variation, and the extraction of new information on local interplanetary transport parameters (including magnetic helicity) from the data; o detailed observational testing of new ideas as to the factors governing cosmic ray mean free paths, including the influence of turbulence dissipation, dynamics, and geometry; and o development and implementation of new observational methods to determine turbulence geometry, placing special emphasis on the identification and measurement of a possible two-dimensional component.
