Epsilon benchtop X-ray tube

The Epsilon X-ray tube is originally designed and optimized for Malvern Panalytical's Epsilon 4 and Epsilon 1 range of energy dispersive (EDXRF) benchtop spectrometers. The tube is a low-power 15 W metal ceramic tube encapsulated in silicone-rubber. The compact X-ray tube with W-anode, is also well suited for other applications such as gauging of web and coating thickness.

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.
