Abstract

X-rays were first discovered in 1895 by Rontgen. Since then, various applications, such as computer tomography, radiotherapy, and X-ray microscopy, have been developed. The size of the X-ray source remains too big for portable use. The objective of this research is to explore the technology of a miniature particle accelerator that can be used as an X-ray source. Such a miniature particle accelerator can store an electron beam using a storage ring. The storage ring in this thesis is designed to store electrons of the MeV energy range. The MeV electrons can be used to generate X-rays by Bremsstrahlung and Inverse Compton Scattering. This type of miniature X-ray source could be used in the battlefield or at an accident site. Several analytic and computational techniques were used to simulate the storage ring. The design of the storage ring was simulated using Opera and Autodesk Inventor. Results of the simulation in Opera show that the charged electrons circulate the storage ring 1000 turns without leaving the equilibrium trajectory. The kinetic energy of the charged particles is 100keV. The simulation structure was fabricated using cast iron and permanent magnets. The fabricated storage ring has a diameter of 114mm and a height of 57mm. The angle of the center cone inside the Betatron structure is 43.360 which was found through design to be optimum for implementing a storage ring.
