The focusing cup is located at the:

Explanation:
The focusing cup is located at the cathode. It sits around the heated filament inside the cathode assembly and is negatively charged to shape the electric field, directing electrons toward the anode target for a tight, well-defined beam. This electrostatic focusing helps produce a sharper focal spot on the anode and reduces beam divergence. The anode is the positive electrode where X-rays are produced; the tube window is simply the exit area for X-rays; the control panel is outside the tube for operating the unit.
