Introduction to the X-ray system
XT H 225 X-ray System XTM0522-B1 27
4.3 System options
Multi-metal target
The standard tungsten target gives an X-ray energy spectrum which contains the
Bremsstrahlung spectrum and the specific emission lines of tungsten. For some materials, in
particular composites, it is often better to have the specific emission at lower energies; this
can be achieved by using different materials as a target. Using the multi-metal target, the
operator can select one of four materials in the target: tungsten (W), silver (Ag), molybdenum
(Mo) and copper (Cu).
Advanced filter kit
The advanced filter kit helps produce the best quality CT metrology conditions using the
multi-metal target.
Sample holders
A selection of additional sample holders is available to increase the flexibility of the
XT H 225. These include:
• Self-centring chuck
• Self-centring vice
4.4 Monitor and console arm adjustment
Adjust the height of the monitor and console
The monitor and console arms are heavy. It is recommended that two
people perform these adjustments, one to support the arm and one to
adjust the locking rings.
Ensure that there is enough free cable to the monitor or control
console before attempting to move them.
The amount of force needed to move the monitor arm and control console arm can be
adjusted by tightening or loosening the resistance grub screws located at each hinge point.
Both the monitor arm and console arm are secured on a bar with lockable clamps. To
change the height of either, first slacken the resistance grub screws located in each arm.
Next, support the weight of the arm whilst loosening the hexagonal cap head bolt in the
retaining clamp until it is moveable. Slide both to the desired position and re-tighten the
clamp bolt. Adjust the resistance grub screws to suit.
