5. MAINTENANCE
5.1 Cleaning the Surface of a Target
(1) Remove any burnt material buildup on the central part using fine sandpaper.
Except Cu, be sure to polish the surface of a target along the circumference. Polishing the target
surface toward the axis may cause dust scraped off from Cu, which is the cup's main material,
and improperly enter an area other than the central section of Cu, thereby causing an adverse
effect on measurements. To prevent scraped Cu dust from improperly entering, first tape the
central section of Cu, then polish the target surface. After polishing the target surface, wipe it
thoroughly clean.
The limit you can polish the surface of a target is 0.1 mm (0.2 mm in diameter).
(2) Wipe clean any oil or dust on the target surface with a cloth or paper moistened with hexane or
similar solvent.
5.2 Inspecting and Servicing the Cooling-Water Seal
The TARGET WATER LEAK ALARM the X-ray generator issues indicates that the carbon ring
on the water seal unit needs to be replaced.
It is recommended to replace the carbon ring at intervals of 3000 hours. The warranty is good for
a period of 3000 hours or one year after delivery, whichever occurs first.
5.3 Failures: Insufficient Vacuum, Rotational Noise, or Heavier Vibrations
The Rotor Target is equipped with a magnetic fluid seal to produce a vacuum. The VACCUM
ALARM the X-ray generator issues indicates that the magnetic fluid seal may possibly need to be
replaced.
If the Rotor Target has louder rotational noise or heavier vibrations, the bearings supporting the
rotational axis need to be replaced.
It is recommended to replace the bearings at intervals of 3000 hours. The warranty is good for a
period of 3000 hours or one year after delivery, whichever occurs first.
Note that, however, replacement and adjustment must be done in our factory.
5.4 Notes on Water Quality
(1) Use cooling water for the Rotor Target which satisfies the requirements stated in the
specifications and the instruction manual of the X-ray generator you use.
(2) Using polluted cooling water causes precipitation of foreign substances and corrosion in the
Rotor Target which may lead to critical malfunction. If you observe the cooling water getting
polluted, replace it immediately.
