By fully utilizing the possibilities of ceramic design, a very close coupling of the anode to the sample was realized, yielding a high intensity at low power settings. Furthermore, the Epsilon tube can operate over a wide range of kV/mA settings, maintaining high power and intensity at even low kV. This flexibility enables selection of optimum excitation conditions resulting in excellent analytical performance, even for the light elements like F, Na and Mg. In addition a Be window with a thickness of only 50 µm increases the light-element performance even further.
The compact metal-ceramic design allows for a very close coupling of sample to anode, yielding high intensity at low power settings. Furthermore, the Epsilon tube can be operated over a wide range of kV settings (4 - 50 kV), enabling high power and intensity even at low kV.
The metal-ceramic design of the Epsilon tube ensures a much better stability of X-ray output than in traditional glass tubes. This results in excellent stability throughout the entire life time of the tube.
