Abstract
The observability of the recently described helical Cerenkov effect, which exists in the microwave to visible spectrum, is discussed. From the kinematics point of view, we show that microwave radiation with the wavelength of 10-1 cm could occur in a medium with the index of refraction of 1.4, beam energy of 3 MeV, and the uniform magnetic field of 4 T. In the visible spectrum with the central wavelength of 5 X 10-5 cm, however, the observability of this effect is achieved with up to 3 MeV in beam energy, silica aerogel as a medium with the index of refraction of 1.075, and uniform magnetic fields from 5 to 10 T. Specifically, for the 10-Tesla magnetic field, it is estimated that, in the 250- to 750-nm visible region, an electron generates a photon through an interaction length of 10 cm. As such, this effect could possibly be used as a detector of radiation by energetic electrons that are trapped in a medium by strong magnetic fields.
