Verification scope and classification notes
- Do not infer the machine's installation country from the developer's U.S. office when mapping it.
- No primary source explicitly identifying the machine's location was verified.
- Editorial classification of the purpose described in official sources; not necessarily the operator's formal classification.
- No item was verified in this review. This does not establish that none exists or that it is undisclosed.
- The 1.6 GPa figure from 2025 is total pressure assuming equal electron and ion temperatures. The newer 2.6 GPa figure is also a preliminary company report, not a peer-reviewed result.
