Abstract :
This study presents diamond film growth, preparation, and characterization using microwave plasma-assisted chemical vapor deposition for gyrotron window materials intended for fusion plasma ignition in magnetic and inertial confinement fusion such as ITER. A surface polishing technique is utilized to polish the films to a mirror grade surface finish. A fine-grained film surface morphology is realized to avoid any deformation caused by shock wave fronts during compression.
