Production of X-Radiation

Across
___ When the exposure button is pushed, the high voltage circuit is activated. The electrons from the tungsten filament in cathode are accelerated to the anode. The distance between the cathode and anode is only ½ in apart. The _________ cup in cathode directs the electrons to the tungsten target.
___ The current is directed to the _______ filament circuit and the step-down transformer. The step-down transformer reduces the 110-220v to 3-5v

___ The size of the x-ray beam is restricted by the lead _______ and exits the tubehead and travels down the PID
___ The x-rays are sent out from the tungsten target out the ______ glass window, to the tubehead seal, and through the aluminum disks. The aluminum disks remove or filter the long x-rays from the beam.
Down

___ The 3-5v is used to heat the tungsten filament of the cathode in the tubehead. _________ emissions occurs, this is the release of electrons in the tungsten filament from the heat of the filament. A cloud of electrons sits at the cathode until the high-voltage circuit is activated.
___ The Heat produced from the production of an x-ray is carried down the coil stem and absorbed by the _______ oil in the tubehead.
___ The electricity from the wall outlet supplies the power to produce an x-ray. When the x-ray machine is turned on the current comes from the wall to the control panel, to the electrical wiring through the______ arm and to the tubehead.
