为超低温（T<100 mK）中子散射实验研制了一个压力室（最大工作压力为100 bar），它采用了布里奇曼密封设计，这种设计在超低温范围内的高温实验中更为常见。大体积的细胞（约18立方厘米）和高强度铝合金的结构使其适合非弹性中子散射实验。该电池已经在操作中进行了验证测试，以寻找氦-4的超固态。
A pressure cell (maximum working pressure of 100 bars) has been developed for neutron scattering experiments at ultralow temperatures (T<100 mK) which makes use of a Bridgman seal design more usually seen in higher temperature experiments in the kilobar range. The large volume of the cell ( approximately 18 cm3) and its construction from a high-strength aluminum alloy make it suitable for inelastic neutron scattering experiments. The cell has been proof tested in operando in search for the supersolid state of helium-4.
