1. IntroductionUltra-high-pressure (UHP) technology has been widely applied in scientific research and industrial production. Consequently, this has increased the urgency of the need for high-pressure, large-cavity, and UHP devices suitable for the measurement of various material properties. Against this background, a number of new UHP devices have emerged [1,2]. UHP devices can be divided into two categories, according to the reasons for pressure generation.
