1. GENERAL
This instruction manual describes the installation and maintenance procedures for the Rotor Target,
which is to be mounted in the high-intensity X-ray generators. For the X-ray generators in which the
Rotor Target can be mounted and the other related equipment, refer to their respective manuals.
It is also well to remember that the Rotor Target needs to be repaired or serviced in our factory to

4. INSTALLING THE ROTOR TARGET IN AN X-RAY TUBE
4.1 Unpacking
(1) Check the packing for breakage and other abnormality.
(2) After unpacking, check all supplied items with a LIST OF SUPPLIED ITEMS (section 3).
(3) Check for no flaw on the surface of the Rotor Target. Stripes on the surface of the Rotor Target
are the traces of electronic beams and do not constitute any problem.
4.2 Mounting the Rotor Target in an X-ray Tube
(1) Carry the Rotor Target by securely holding the body of it.
Never carry the Rotor Target by holding its cable or target drum. In addition, do not give any
shock to the target drum.
(2) Wipe the part of the Rotor Target body to be inserted into the X-ray tube with a cloth or paper
moistened with hexane or like solvent. Use care so that the solvent does not flow into the body.
Do not directly touch the said part by your hand.
(3) Wipe the O-ring to be attached to the flange of the Rotor Target with a clean cloth or paper.
Also, thoroughly wipe off any dirt from the O-ring groove of the body and the part of the X-ray
tube at which the O-ring is engaged.
(4) Firmly hold the body, and slowly insert into position while aligning it with the X-ray tube
mounting port. Use extreme care so that the circumferential surface of the body does not bump
against anything.
(5) Make sure that the flange on the Rotor Target body is in proper contact with the X-ray tube, and
then tentatively tighten the four mounting screws by degrees and in turn.
(6) Properly connect the two connectors of the body.
(7) If a plug is attached to the cooling-water hose fitting, pull it out pushing the ring on the fitting.
(8) Properly connect the cooling-water hose to the body, aligning the label on the hose with the label
on the body (by strongly pushing the tip of the hose into the fitting).
(9) Insert the leakage sensor to the fitting on a side of the body.
(10) Turn ON the circuit breaker and the main power. After it starts emitting exhaust, firmly tighten
the four mounting screws by degrees and in turn.
Note: Before attaching or removing the Rotor Target, be sure to turn OFF the X-ray
generator power, wait for at least 30 minutes after it stops to emit exhaust and
until the TMP revolutions fully drop to a speed safe to handle.

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.

5.5 Example of a Maintenance Record
To prevent accidents and assure smooth servicing in the event of an accident, you should record the
contents of servicing and repairing tasks performed.
A typical maintenance record example is presented below (the hour meter indicates a reading on
the hour meter of the X-ray generator):

5.6 Other Precautions
(1) Store the Rotor Target in a place where there is neither high temperature nor high humidity to
prevent it from deteriorating.
(2) In replacement of a target, use care so that water drops remaining within the cooling water hoses
do not come into contact with the target surface or the inside of the body of the Rotor Target.
(3) It is recommended that the environmental conditions of the room be properly maintained so as to
avoid moisture condensation during equipment use. Using the Rotor Target in an unfavorable
environment (e.g., high temperature or humidity) may influence the parts in it and deteriorate the
performance it can really provide.
(4) When removing the body of the Rotor Target from the equipment (i.e., to change the target
material), be sure to turn OFF the X-ray generator power, wait for at least 30 minutes after it
stops to emit exhaust and until the TMP revolutions fully drop to a reasonable speed.
(5) For use of any solvent to wipe clean the Rotor Target, exercise utmost care to provide adequate
ventilation and keep fire away at the work site.

5.7 Typical Problems and Remedies
Problem Probable cause Remedy
Water leakage occurs. There is foreign dust on the
surface of the seal, or
the water seal unit has
reached the end of its useful
life.
Replace the water seal unit.
The connector connection is
not properly made.
Check for the proper connector
connection or the retaining screws
whether properly tightened.
There is an alarm issued for
the target driver.
Solve the cause of the alarm, then turn
the power OFF on the operation panel
and turn it ON again.
The target does not rotate.
There is water in the
connector (e.g., the cooling
water in a hose might have
entered during target
replacement).
Immediately turn OFF the X-ray
generator power, disconnect the
connector, and thoroughly dry the
inside of the connector.
Abnormal noise is
generated.
Vibration is increasing.
The bearings are faulty. Replace the bearings.
