| Abstract | ||
| A study it was presented to understand the behavior of charged particles beam through consideration systems of double Quadrupole Triplet Electrostatic Lenses reaching to the optimum design. In this work , tracing the path of charged particles beam has been done within the free field space and double quadrupole electrostatic lens, by using matrices to described particle trajectories throughout the system, matrix representation deals with ion beam as bunched and representing phase ellipse for both horizontal and vertical planes. The present work investigate the effect of changing the main parameters of double Quadrupole Triplet Electrostatic Lenses such as [extraction region shape, length of quadrupole, the distance between the quadrupole lenses, voltage applying on lenses and second field free region length]. A computer program written in (MATLAB) language to trace the path of charged particles beam with a system of double Quadrupole Triplet Electrostatic Lenses has been built in the present work. The results indicate good focusing properties. | ||
