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.

研究3HE阶段，温度，磁场，压力和边界效应的非线性超流量的磁性水力学的实验。 另一个实验将通过“磁性自旋滤波器”迫使超流体增加极化，然后表征流体的粘度以与最近的理论进行比较。 第二个声音将用于测量3HE超流体的导热率。 另一个实验将测量第四声音的衰减，边界条件被4HE涂层改变。
