Commissioning a Fusion Machine

The staged turn-on from cold systems to first plasma to demonstrated performance.

Operations & CommissioningUpdated 2026-08-11
Path
Cold → first plasma → power

Commissioning takes a built machine from individual cold systems, through integrated cold checks, to first plasma and then a staged climb to full performance. Each stage has entry and exit criteria, and nothing advances until the prior stage passes. It is the disciplined bridge between construction and operation.

Kronos frames the commissioning sequence explicitly as part of its path to build.

Common questions

What does commissioning a fusion machine involve?

Taking each system from cold, then integrating them — energising magnets, pumping down, validating interlocks — up to first plasma, with entry and exit criteria at every stage.

Can stages be skipped to save time?

No — nothing advances until the prior stage passes. That discipline is how a complex new machine is brought to life safely rather than quickly.
