Value chain · CLM-0069
In plain terms
The runaway threshold barely changes with atmospheric conditions. It is decided by the choice of frequency, not by the state of the atmosphere.
The claim as recorded
The thermal runaway threshold is insensitive to ionospheric conditions, varying by only about 11 per cent across a neutral temperature range of 170 to 210 K at 100 km altitude, because its dependence is only temperature to the power minus one half; it is set almost entirely by the design frequency.
Scope and limits
Applies only to the thermal runaway mechanism, not to self-focusing. And it is moot if CLM-0056 holds, since that records the runaway mechanism as having been refuted in 1981 as a transport coefficient artefact.
What it assumes
neutral temperature at 100 km spans roughly 170 to 210 K, which is provisional pending profile data
Where it comes from
This is the project's own working, shown in full:
At 2.45 GHz the relation gives 129 W/m2 at Tn = 170 K, 119 W/m2 at 200 K and 116 W/m2 at 210 K. CALC-007 shows the working. Applying the document's stated factor-of-two uncertainty to the 200 K case gives a band of 59 to 238 W/m2 at 2.45 GHz.
