2 PURPOSE AND CHARACTERISTICS
Each plug-in consists of a pre-adjusted X-ray tube in a
sheet steel housing with a handle. All plug-ins are sup-
plied ready for use in the basic XR 4.0 X-ray expert
unit.
•
Pre-adjusted tubes with quick-change technol-
ogy
•
Hot parts contact protection
•
Housing with ratchet and pawl mechanism and
2 safety contact pins which only unlock for tube
operation when a plug-in has been correctly
inserted.
3 FUNCTIONAL AND OPERATING ELEMENTS
The following ready for use plug-ins are available:
•
Plug-in with Cu X-ray tube, article no. 09057-51
•
Plug-in with Mo X-ray tube, article no. 09057-61
•
Plug-in with Fe X-ray tube, article no. 09057-71
•
Plug-in with W X-ray tube, article no. 09057-81
(For wavelengths and energies of the characteristic X-ray
lines refer to the Technical specifications and the Appendix).
Each plug-in consists of a factory-adjusted X-ray tube in a
sheet steel housing. To prevent damage from overheating,
each tube is enclosed in a Duran glass cylinder which has
side tubes for forced air cooling via the fan in the basic de-
vice.
Each plug-in is equipped with an HV plug and a plug for tube
cathode heating. Tube operating parameters can so be
picked up via the corresponding sockets of the basic device.
Two metal pins at the sides release a safety micro-switch
which safeguards the tube plug-in chamber on correct inser-
tion of an plug-in.
4 NOTES ON OPERATION
Handle with care!
First start up:
X-ray tubes are not to be operated under full power on their
first start up. For the running-in of a tube we recommend that
you first operate it for a period of 10 minutes with a maximum
beam current but with an acceleration voltage which is not
above 25 kV.
This procedure must be repeated when a tube has not been
used for a period of some weeks.
•
Minimum life time of the tube: 500 operating hours
5 HANDLING
Handle with care!
Inserting and changing X-ray tube inserts:
Stop X-ray tube operation before carrying out a change
of plug-ins.
Plug-ins must be removed without tilting them. To insert an
plug-in, fit the guide tabs in the guide rails without tilting the
plug-in. Ensure that all plug connections have secure contact
by pushing the plug-in in to the stop.
