Cosmic Ray Modulation Using Ground-Based Neutron and Spacecraft Cosmic Ray Detectors

在提议的努力中，PI将继续运行华盛顿山和达勒姆的宇宙射线中子监测器，直到下一个调制最小值（1996-97），以及继续研究将地面宇宙射线观测与近地宇宙射线望远镜数据联系起来。PI计划研究的具体问题有：(1)行星际宇宙射线的径向和纬度梯度；(2)利用宇宙射线确定终端激波和宇宙射线调制边界的位置；(3)宇宙射线强度电荷与日球层电流片相关性的意义；(4) 11年宇宙射线强度周期的恢复阶段；(5) 22年周期，历次最强强度的比较；(6)瞬态刚度依赖性减小；(7)太阳宇宙射线事件。

In the proposed effort, the PI will continue the operation of the cosmic ray neutron monitors at Mt. Washington and Durham through the next modulation minimum (1996-97), as well as continuing studies which relate ground-based cosmic ray observations to near- Earth cosmic ray telescope data. Specific problems the PI intends to investigate are: (1) the interplanetary cosmic ray radial and latitudinal gradients; (2) location of the termination shock and cosmic ray modulation boundary using cosmic rays; (3) significance of the correlation of the cosmic ray intensity charges and the heliospheric current sheet; (4) recovery phase of the 11-year cosmic ray intensity cycle; (5) the 22 year cycles...comparison of the intensities at successive intensity maxima; (6) rigidity dependence of transient decreases; and (7) solar cosmic ray events.
