Instrumentation, Control & Safety

The sensors, controls and interlocks that run the machine safely.

Layers

Diagnostics, control, safety interlocks

Diagnostics measure the plasma; a control system steers heating, fuelling and magnets; and an independent safety-instrumented system enforces interlocks. Functional-safety standards govern the interlock design.

Control and safety are treated as detailed-design-ready subsystems whose qualification (SIL verification) is a scheduled, not open-ended, task.
