Remembering A.A. Korchak

Interesting link about Korchak! I visited him long ago (perhaps 1972?) in Troitsk, aware that he could not travel but not knowing that he was a founding member of the Moscow Helsinki group.

I don't think they were founded until 1975. I heard something similar, that he couldn't travel, from John Brown. I wonder if this is the same man: http://search.barnesandnoble.com/Totalistic-Organizations/A-Korchak/e/9780880339940

Lorentz factor

If you have high Lorentz factor (\gamma>100) electrons most of their energy will be lost by synchrotron radiation in a magnetic field of about 100 G. The photon energy density in the photosphere is equivalent to 7 G, so only <1% of the electron energy will go into X-rays requiring a huge energy input. Most of the energy will come out in sub-mm and micron region. I think there are some limits in this wavelength range.

thanks, Vahe, an interesting comment. I'm sure you're right, if we worry about the overall evolution of the electrons. But this doesn't preclude them making a faint but detectable X-ray source in the corona, even if the bulk of their radiative output does actually outcome at other wavelengths. That's the possibility we were interested in.
