Design Parameter Callouts
Callouts present a component's key parameters with their conditions, so a number is never shown without the context it needs.
Numbers with their conditions
A fusion parameter without its conditions can mislead. A field value means little without saying where it is measured; a gain figure means little without saying against what input. The model's callouts always pair a number with the condition that makes it meaningful, following the Kronos practice of quoting frozen values together with their caveats.
Examples of conditioned callouts
- Field 8 T on axis, 16.84 T peak on the conductor, two values because the field varies with radius.
- Q 3.424 at 88.7 MW fusion power, a simulation result, gain stated against the power it refers to.
- 26.49 T at the burner plug, 17 T at the throat, each tied to its location on the axis.
- Neutron fraction 5.44 percent of fusion power, the denominator stated explicitly.
Why this discipline
Stating conditions keeps the model honest and keeps its numbers usable. A reader can carry a callout into the design papers and check it, because they know exactly what it refers to. It also prevents the common failure of quoting a peak conductor field as if it were the field the plasma sees, or a fusion gain as if it were a net-electric gain.
Gates and caveats
Where a parameter depends on a physics gate that has not been demonstrated, the callout says so. The model makes no hardware net-gain claim before the first Hyperion unit reaches first tritium around 2030, and its callouts reflect that: computed design points are labeled as computed, not as achieved.
Reading them
Callouts appear on selection and expand in cutaway. See Component Measurements for the full parameter set and The Model as Design Record for the honesty stance behind them.
