Paper Abstract

The helical Cerenkov effect as a novel radiation source, we believe, should be observable from microwave to visible wavelengths. From the kinematics point of view, 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 Tesla. 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 Tesla. Specifically, for the 10 Tesla magnetic field, it is estimated that in the 250 - 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.
