Preliminary results on the study of radiation from positrons in a periodically deformed crystal
2006
In the present experiment, the radiation from positrons moving in a periodically deformed crystal was observed for the first time. The spectra of radiation are measured in a wide range of energy. The experimental indication showing the existence of an undulator peak in radiation was obtained at a qualitative level and was confirmed by calculations. Crystal undulators provide an equivalent magnetic field of 1000 T and periods in the submillimeter range and consequently can be applied to the generation of X-rays and gamma-rays, of energies a hundreds times higher than the radiation in usual undulators.
