RESEARCH RESULTS FROM N.A. KORKHMAZYAN AND COLLEAGUES UPDATE UNDERSTANDING OF TECHNICAL PHYSICS
Science Letter
October 20, 2009
According to recent research from Yerevan, Armenia, "X-ray radiation
from fast electrons in undulators filled with an inverse medium is
studied. A formula for the spectral density of the number of photons
is derived."
"The intensity zeroth harmonics, as well as the intensity of radiation
in zero undulator field, are described by the Tamm-Frank formula for
Cherenkov radiation. It is shown that the spectral density of emitted
photons in a wavelength range of lambda a parts per thousand...
0.4-2.0 in such a medium can be increased by four orders of magnitude
as compared to the radiation intensity in a vacuum undulator," wrote
N.A. Korkhmazyan and colleagues (see also Technical Physics).
The researchers concluded: "The energy of emitted electrons in the
former case must be in an interval of 5-2 GeV, while electrons with
an energy of 14-6 GeV are required in vacuum undulators."
Korkhmazyan and colleagues published their study in Technical Physics
(Hard undulator radiation in an inverse medium. Technical Physics,
2009;54(9):1392-1394).
