用活塞圆柱装置获得了金属铯在42.5和43毫巴两个跃迁以上的粉末中子衍射数据。Lucalox圆柱体（高密度Al2O3）（35.4mm外径，6.35 mm内径）通过用液压压头压缩两块钢板来径向支撑，在板之间留下约6mm高的中子窗。在圆柱体和支撑板之间使用17°夹角。碳化钨活塞由第二个液压柱塞驱动，以支撑压力增加速率的三倍增加样品上的压力。
Powder neutron diffraction data have been obtained on cesium metal above the two transitions at 42.5 and 43 kilobar using a piston cylinder apparatus. A Lucalox cylinder (high density Al2O3) (35.4 mm o.d., 6.35 mm i.d.) is radially supported by compressing two steel plates with a hydraulic ram leaving a neutron window between the plates ∼6 mm high. A 17° included angle was used between the cylinder and support plates. A tungsten carbide piston, driven by a second hydraulic ram, raised the pressure on the sample at three times the rate of increase of the support pressure.
