Oscillations and Superradiance in Radiation Spectrum of Electrons Moving in Spiral in Medium
نویسنده
چکیده
The fine structure of the synchrotron-Cherenkov radiation of spectral distribution of the radiation power of one and four electrons moving in a spiral in a transparent medium with relativistic transversal velocity component (the component perpendicular to the magnetic field) is researched. The oscillations and superradiance in the synchrotron-Cherenkov radiation spectrum of four electrons at different time shifts between electrons are investigated. The influence of the coherence factor on the spectrum of synchrotron-Cherenkov radiation for four electrons is analyzed.

Radiation spectrum of an electron moving in a spiral in medium
The action of the Doppler effect on the particularities of radiation power spectral distribution of an electron moving in a spiral in a medium has been investigated near the Cherenkov threshold. The fine structure of the electromagnetic radiation spectrum at the Cherenkov threshold and the synchrotron-Cherenkov radiation spectrum for an electron moving along a spiral with non-relativistic longi...
متن کاملInvestigation of Charged Particles Radiation Moving in a Homogeneous Dispersive Medium (TECHNICAL NOTE)
In this work, we use Drude-Lorents model description to study the radiation of a charged particles moving in a homogeneous dispersive medium. A suitable quantized electromagnetic field for such medium is utilized to obtain proper equations for energy loss of the particle per unit length. The energy loss is separately calculated for transverse and longitudinal components of the filed operators. ...

Inertial motion superradiance, the emission of radiation by an initially unexcited system moving inertially but superluminally through a medium, has long been known. Rotational superradiance, the amplification of radiation by a rotating rigid object, was recognized much later, principally in connection with black hole radiances. Here we review the principles of inertial motion superradiance and...

متن کاملCalculation and evaluation of energy deposition and S-value caused by low-energy electrons in a multicellular model using Geant4-DNA
Today, targeted radiation therapy (TRT) methods for cancer treatment, besides the goal of completely destroying the target tumor, attempts to prevent nearby healthy cells from exposure to ionizing radiation as far as possible. Hence, short-range charged particles, such as low-energy electrons that are suited to achieving these two goals together, play an important role in TRT and so, adoption o...
