The Digital Twin in the Path

A predictive digital twin integrates MetroVolt’s models into a machine-level simulation used to design, plan tests, and later to operate.

One integrated model

Individual codes model pieces — plasma, magnets, DEC, thermal loads. A digital twin integrates them into a single predictive model of the whole machine. For MetroVolt at design stage, the twin is where subsystem models are made consistent and where machine-level behavior is explored before any metal is cut.

The twin serves three roles across the timeline: it sharpens the design now, it plans and interprets the ~2032 test unit, and it becomes an operational tool once hardware exists — running alongside the machine to predict, control, and diagnose.

What the twin is not

A digital twin is only as good as its models. It does not confirm physics on its own; it inherits every uncertainty in its inputs, including the open confinement and DEC questions. Its value is disciplined integration and fast exploration, not proof. The test unit remains the arbiter.

• Integrates subsystem models into a machine-level prediction.
• Designs now, plans the test, operates later.
• Carries — does not resolve — the underlying physics uncertainty.

The twin is a central tool of the design stage and a bridge to operations, which is why it appears throughout the readiness path.
