Image Intensifier Tube and Power Supply
The Image Intensifier (II) Tube is a cathode ray tube mounted on the end of the C-weldment opposite the X-ray Tube. The II
Tube and Power Supply are contained beneath the II cover. The CCD Camera is mounted on the bottom of the II assembly.
The II tube receives the x-rays and produces a bright reduced-size image on its bottom phosphor glass plate. The camera sends
a video picture to the Workstation monitors of the x-ray image projected on bottom II output plate.

Image Intensifier Tube and Power Supply
A power supply attached to the II housing produces the voltages needed for the internal electrostatic focusing and deflection grids
of the II. The II is available in 9- or 12-inch sizes. The normal operating mode is supported by both II sizes, plus two levels of
magnification.
The II Power Supply mounted on the II tube assembly powers both the 9- and 12-inch II versions. The power supply operates on
+24 volts from System Power Supply PS2. The Fluoro Functions PCB controls the II power supply. This PCB varies the grid
voltages to the tube in accordance to the mode in which the II is to operate. The II Power Supply also generates the II tube
anode voltage, with a maximum of 29.5 kV.
