Development of an Occluded‐Gas Ion Source

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Ion Source Development and Operation

A new vacuum arc type ion source (VARIS) has been developed and tested for high current uranium operation. Figure 1 shows a cross sectional view of the ion source. The discharge arrangement has a tubular anode opposite to the cathode mount carrying 17 cathodes (each one is 5.7mm in diameter and 17mm in length). The anode, made of stainless steel, is placed 15mm apart from the cathode. Its apert...

Development of a microwave ion source for ion implantations.

A microwave ion source is expected to have a long lifetime, as it has fewer consumables. Thus, we are in the process of developing a microwave ion source for ion implantation applications. In this paper, we report on a newly developed plasma chamber and the extracted P(+) beam currents. The volume of the plasma chamber is optimized by varying the length of a boron nitride block installed within...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Field ion source development for neutron generators

An ion source based on the principles of electrostatic field desorption is being developed to improve the performance of existing compact neutron generators. The ion source is an array of gated metal tips derived from field electron emitter array microfabrication technology. A comprehensive summary of development and experimental activities is presented. Many structural modifications to the arr...
