Description
Summary:Synchrotron-Čerenkov radiation can significantly alter optical emission in the vicinity of the Čerenkov threshold. A convenient illustration is provided by 20-MeV electrons passing through ethene gas in a 5-kG field. For ethene densities of the order of 0.5. gm/l, or about 40% STP, the experimentally observable intensity of green light (ω∼2.4 eV) is expected to be amplified by five orders of magnitude over the levels predicted by a simple superposition of synchrotron and Čerenkov radiation.
