Design and Establishment of an Implementation to Simulate and Analyse the Tertiary Undulator of the FEL

Abstract

This paper discusses how the power of the free electron laser (FEL) beam was increased without increasing the size of the laser device by using a new model with a different technique for the undulator; the purpose of this technique is to make full use of the undulator magnets in a three-row system instead of the two-magnet system. This technique reduces the size of the laser device by decreasing the undulator’s length and controlling the path of electrons within the rows of the undulator magnets. From the analysis of the obtained simulation results, it can be concluded that it is possible to make the FEL device with double the power output without increasing the size of the device; this will increase future applications of the FEL in the civil and military fields.

Analysis and Simulation the Effect of the Pierce Parameter on the Output of the Free Electron Laser system

“…The most important characteristic of the resulting free electron laser is the possibility of tuning the wavelength and the power of the output laser to any required value according to the following equations [1,6,12,13,16,17].…”

“…The relation between the pierce parameter and the number of coherent photons is given by the equation [5,15,17,19,20]…”

“…The growth rate continues to increase until it reaches saturation state. The gain length and saturation power represent the main parameters to determine the performance of the FEL system, both depend on the Pierce parameter according to the following Equations [5,8,15,17,18,19,21]:…”
