Advanced multi-anvil technology
There are many websites to explain the multi-anvil experiment. Please visit those pages to obtain general understanding of the multi-anvil experiment. I especially suggest the following pages.
In addition to the excellence of the multi-anvil experiment, we have the following advanced high-pressure-temperature experimental technologies using multi-anvil presses, allowing us to conduct unique research.
- Ultrahigh-pressure generation. We can generate pressures up to 50 GPa, corresponding to the depth of 1500 km in the Earth [Ishii et al., 2019; Ishii et al., 2022]. This pressure range is twice broader as in other laboratories (25 GPa).
- Ultrahigh-temperature generation. We can generate temperatures up to 3000 K, which is 1.5 times broader than others (up to 1800 K) [Nishida et al., 2020; Xie et al., 2021]. This technique allows us, for example, to melt peridotite completely.
- Homogeneous temperature field. We can generate a highly homogeneous temperature field using the zero-temperature gradient furnace to prevent solid-melt segregation and investigate partial-melting rocks [Zarei et al., 2017].
- Advanced in situ X-ray observation. We have an advanced technique of synchrotron in situ X-ray observation to determine phase relations accurately [Katsura, 2007; Ishii et al., 2018; Ishii et al., 2019; Chanyshev et al., 2022].
- Rapid-quench technique. We can quench hydrous and ultramafic melts into glasses with ten times faster cooling rates [Bondar et al., 2020; Bondar et al., 2021]. This technique allows us to investigate the properties of mantle melts using various post-analysis [Bondar et al., 2022].
