It can generated in periodic materials via the Smith-Purcell effect. This phenomenon is exploited in the Sudbury and Super-Kamiokande detectors, where it is generated by interactions with passing neutrinos. The cosine of its opening angle is given by one over the refractive index times the beta fact
It can generated in periodic materials via the Smith-Purcell effect. This phenomenon is exploited in the Sudbury and Super-Kamiokande detectors, where it is generated by interactions with passing neutrinos. The cosine of its opening angle is given by one over the refractive index times the beta factor. It produces an intensity proportional to frequency, explaining its characteristic blue color seen in water, which is often used as the medium for this effect. For ten points, identify this electromagnetic analogue of the sonic boom which results when a particle passes through a medium faster than the local speed of light.
