Experiments to study magnetohydrodynamics of nonlinear superflows in Al phase of 3He, varying temperature, magnetic field, pressure and boundary effects. Another experiment will force superfluid through a "magnetic spin filter" to increase the polarization, and then characterize the fluids' viscosity to compare with recent theory. Second sound will be used to measure the thermal conductivity of 3He superfluid. Another experiment will measure attenuation of fourth sound with the boundary conditions altered by a 4He coating.

非线性超流磁流体力学实验研究 在Al相3He中，温度、磁场、压力 边界效应。 另一项实验将迫使超流体 通过“磁性自旋过滤器”来增加极化， 然后描述流体的粘度， 最近的理论 第二个声音将被用来测量热 3He超流体的电导率 另一个实验将测量 边界条件改变时第四声的衰减 4He涂层。
