<br/><br/> The aim of this thesis is to improve the performance of a new shape cold cathode Penning ion source to be suitable for some applications . In this work , many trials have been made to reach the optimum dimensions of the new shape of cold Molybdenum cathode Penning ion source with radial extraction . The high output ion beam can be extracted in a direction transverse to the discharge region
