Abstract: A method for synthesizing a diamond by chemical vapor deposition, the method may include heating at least one internal space of at least one hot filament unit; wherein the at least one hot filament unit is positioned in a vacuum chamber; wherein a volume of each internal space out of the at least one internal space is smaller than one half of a volume of the vacuum chamber; feeding at least one gas to the at least one internal space; wherein the at least one gas comprises at least a carbon carrier gas; breaking the at least one gas by the at least one hot filament unit, to provide at least one radical; and depositing the at least one radical on an area of a substrate to provide the diamond.
