为了解决金属腔中涡流加热和洛仑兹力的问题，研制了一种塑料螺丝扣金刚石对顶砧（DAC）和一种非金属垫圈。塑料单元由我们的空的6.3 mm金属螺丝扣DAC演变而来，该DAC于1993年设计，可在Quantum Design MPMS的9 mm样品空间中旋转。在脉冲磁场中使用这种金属DAC的尝试导致样品温度上升到T > 70 K，需要构造非导电电池和垫圈。在T = 4K的光学研究中，在具有0.8 mm底托的塑料电池中产生了3 GPa的压力。细胞的变化，现在被用于费米学研究的金属系统在脉冲磁场中，需要开发一个转子和一个特殊的He-3低温恒温器也进行了讨论。
A plastic turnbuckle diamond anvil cell (DAC) and a nonmetallic gasket have been developed for pulsed magnetic field studies to address issues of eddy current heating and Lorentz forces in metal cells. The plastic cell evolved from our empty set 6.3 mm metal turnbuckle DAC that was designed in 1993 to rotate in the 9 mm sample space of Quantum Design's MPMS. Attempts to use this metal DAC in pulsed magnetic fields caused the sample temperature to rise to T > 70 K, necessitating the construction of a nonconductive cell and gasket. Pressures of 3 GPa have been produced in the plastic cell with 0.8 mm culets in an optical study conducted at T = 4K. Variations of the cell are now being used for fermiology studies of metallic systems in pulsed magnetic fields that have required the development of a rotator and a special He-3 cryostat which are also discussed.
