The One-dimension theory is applied to study the performance of free electron laser amplifier when the electron beam have a uniform density distribution in the direction perpendicular to the helical undulator axis with initial phases uniformly distributed along the interval (0-2π). The matlab 6.1 program is used to built the computer programs that used in this work.In the present work, the motion of electron are considered inside the helical undulator. The equations of motion for electron inside the undulator, show that three effecting parameters, they are:

This study was carried out to prepare a porcelain samples, which can be used as an electrical insulator.  The raw materials used for the preparation are kaolin Duakhla, Arudhma Sand glass and Potash feldspar with weight percentage (45%, 30%, 25%) respectively.  A chemical treatment was performed on kaolin Duakhla, Arudhma Sand glass to remove all the impurities.  The effect of the washing by HCl acid (chemical treatment) was examined by IR Tech.

     With the aid of transfer matrices method and personal computer a computational research has been carried out on the properties of a rectangular model representing the axial field of an electrostatic quadrupole triplet lens.  The path of charged–particles beam traversing the rectangular fields has been determined by solving the trajectory equation of motion in Cartesian coordinates.  A computer program has been written for this purpose.
