A movable X-ray generation apparatus includes an X-ray tube configured to perform irradiation with X-rays, an arm configured to support the X-ray tube, a cart unit configured to support and move the arm, and a monitor mounted on the upper portion of the cart unit. The method includes providing at least one array of carbon nanotubes, a first substrate, and a second substrate. The computer-readable medium includes instructions for the system to implement a method for monitoring the system for modem use. Moreover, the information associated with the components as they are tracked through the manufacture process is used to maintain and enhance the efficient operation of the assembly line.
