A disposable frame in a multianvil 6-6 assembly for a cubic-type multianvil press

Area of Science:

• Materials Science
• High-Pressure Geophysics
• Experimental Physics

Background:

• High-pressure experiments are crucial for understanding Earth's deep interior and material properties.
• Current experimental setups, particularly using multianvil presses, face time constraints at shared facilities like synchrotrons.
• Existing metallic frames for sample assemblies are time-consuming to set up and exchange.

Purpose of the Study:

• To develop a more efficient sample assembly frame for high-pressure experiments.
• To reduce the time and cost associated with sample preparation and exchange in multianvil press experiments.
• To provide adaptable solutions for experiments where sample blowout may occur.

Main Methods:

• Development of a novel plastic frame for a 6-6 compression assembly in a multianvil press.
• Comparison of setup/exchange times and costs between the new plastic frame and traditional metallic frames.
• Evaluation of frame reusability and performance, especially after experimental blowout events.

Main Results:

• The new plastic frame achieved a 90% reduction in sample setup and exchange time compared to metallic frames.
• A subsequent development resulted in an inexpensive, blowout-resilient frame, reducing costs by 40%.
• The plastic frames offer a significant improvement in efficiency for time-limited synchrotron radiation facility usage.

Conclusions:

• The developed plastic frames offer a breakthrough in efficiency for high-pressure experimental sample assembly.
• Both the original plastic frame and the newly developed inexpensive version are valuable additions to experimental techniques.
• The adoption of these frames is recommended to optimize resource utilization at joint-research facilities.
