Sina Jahanbakhsh received his B.Sc. degree from Iran University of Science and Technology.
He completed the M.S. degree at the mechanical engineering department of Bogazici University under the supervision of Assoc. Prof. Murat Celik.
His thesis topic was "Numerical and Experimental Investigation of Inductively
Coupled Plasma Cathode for Electric Propulsion Applications"
Sina has been looking into the concept of plasma cathode devices. These cathodes are introduced as an alternative for the hollow cathodes.
Plasma cathode operation is based on the creating a bulk plasma inside a chamber and applying a positive potential in order to extract the electrons.
Experiments show that applying a sufficiently high bias voltage to the source (or bulk) plasma will create a secondary structure inside the cathode which is known as anode spot or fireball . Formation
of anode spot is the most important feature of the plasma cathode device. Sina has been doing a theoretical investigation about these phenomena.
In the experimental part of his thesis, Sina has manufactured an RF cathode and an RF thruster which have been tested in BUSTLab.
Sina has officially started the research with the group in July 2013, however
during the spring 2013 semester Sina had begun investigating various topics
in his current research field. He has defended his M.S. thesis at August 2015.
