High Power HP Technology for X-Ray Tubes
Since the invention of the X-Ray tube in 1895, the ratio
between focal spot size and power has not improved
significantly.
COMET AG has achieved a breakthrough in this historical
relation with its new High Power (HP) technology. The HP
family of X-Ray tubes has nearly doubled the power density of the conventional fixed-anode X-Ray tube.
The Benefit of the HP Innovation
power with the same focal spot size. With
higher power, shorter exposure times are possible.
The result is higher throughput through the inspection
process.
■Smaller focal spot at the same power. Previously, when
striving for finer resolution, the customer had to sacrifice power (and thus throughput) to achieve a smaller
focal spot. You must no longer suffer this compromise.
■Longer tube life. The lower Anode temperature results
in less thermal stress and leads to a longer tube live.

The Demanding Challenge to Increase the Power
Density of an X-Ray Tube
X-Ray tubes operate in extreme conditions:
■ Ultra high vacuum technology (10–9 mbar)
■ Temperatures up to 1500 ºC
■ Rough environment
■ Expectations to live more than 10 years
1 mm focal spot of a conventional MXR-160/20. At
640 W (maximum power)
the temperature reaches
1500 ºC.
1 mm focal spot of the HP
tube MXR-160HP/20, same
focal spot size, same
power, but with 900 ºC,
a significantly lower temperature. The power can
be increased to 1000 W
before the temperature
reaches 1500 ºC.
To make an X-Ray tube more efficient, one must go to
work on the focal spot, the very small place where the
electron beam strikes the heavy-metal target and produces X-Rays. The power dissipation by a standard X-Ray
tube is approx 300 W/mm2. With our revolutionary new
construction of the anode we reach 600 W/mm2. This
success of COMET’s development team was the result of
the convergence of unconventional thinking, the use of
the latest simulation techniques and more than 50 years
of experience in the construction of X-Ray tubes.

What Are the Trends?
In the coming years, digital detectors will increasingly replace traditional X-Ray techniques such as film and image
intensifiers. The consumer’s demand for cost-effective
products dictates that everything must be more efficient.
Productivity must be increased. Cycle times must be
shorter. With digital detectors, already flux-starved imaging chains will be at their limits just to produce adequate
pictures.
The public’s increasing demand for safer products will
push manufacturers to find even smaller defects, thus
increasing the need for high-resolution X-Ray inspection.
Our Response
To meet the challenges evoked by these trends, COMET
invented the HP technology and thereby revolutionized
the X-Ray industry.
Smaller focal spots with more power enable our customers to develop “best in class” solutions.
Today, COMET offers a broad portfolio of tubes based on
HP technology in the range from 160 kV to 800 kV.
