In plain terms
Self-focusing has actually been seen in experiments, at Arecibo and at HAARP, not just calculated.
The claim as recorded
Thermal self-focusing is an experimentally observed phenomenon rather than a purely theoretical one, having been studied at Arecibo (reported in 1983; CLM-0135 puts the measurements at June 1977) and observed optically and by radar at HAARP in February 2005 (published 2007), where pump-induced striations were reported at 20 to 30 decibels above background (a figure SRC-125 cites to a companion paper rather than measures) with a focus forming below 230 km altitude and observed structures of 2 to 6 km; the imager's pixel resolution at 230 km is about 200 metres, which is not a measured striation scale.
Scope and limits
These are HF heating experiments at 2.85 MHz with an effective power density of 20 mW/m2, not microwave power beams. The frequencies differ by three orders of magnitude and the power densities by four, so this establishes that the instability is real and observable, NOT that it occurs at SBSP frequencies or intensities. SRC-125 also notes its own HAARP experiment sat below the 100 to 300 mW/m2 range of the simulations it compares against.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
cites strong pump-induced striations 20 to 30 dB above background to a companion Kosch et al. 2007 paper (p.5), and records a 1 per cent plasma depletion forming its focus below 230 km (p.6), observed structures of 2 to 6 km (p.8) and an imager pixel resolution of 200 m at 230 km (pp.3 and 8); the experiment ran on 4 February 2005 (p.1). It cites Farley, LaHoz and Fejer 1983, Studies of the self-focusing instability at Arecibo, and Guzdar et al. 1996 and 1998.
