Analysis of angular spectrum of radiation in an undulator magnet

Analysis of undulator radiation with an electromagnet undulator

“…This is a distinctive feature of electromagnet undulators in comparison with PPM based undulators. In the case of PPM undulators, vanadium permendur strips are used to modify the PPM undulator for higher harmonic lasing [11][12][13][14][15][16][17]. In the case of electromagnet undulators, higher harmonic lasing is arguably possible if the electron beam is shifted up and away from the axis.…”

Four - frequency undulator radiation intensity in free electron laser

“…The two frequency and three frequency schemes studied in the past by the researchers. In this paper, we have studied [4][5][6][7][8][9] four frequency undulator scheme with the effect of angular injection and radiation intensity expression [10][11] has been expressed. The trajectory of electron is formulated using Lorentz force.…”
