X-Ray Tubes

The Mini-X2 is a miniature X-ray tube system which includes the X-ray tube, the power supply, the control electronics, and the USB communications to the computer.  It is optimised for compact X-ray fluorescence (XRF) applications.  The Mini-X2 has been designed to simplify the XRF process by providing a grounded anode, USB control of current and voltage, a simple collimator mount on 50kV models, and ease of operation.

The Mini-X2 consists of two components: the Mini-X2 X-ray tube module and the Mini-X2 Controller.

The X-ray tube module includes the tube and high voltage power supply. The Controller includes the USB communications and software control. It can be configured, via software, to support any of the X-ray tube modules. A 10 pin flex cable connects the Controller and the X-ray tube module. Connections to the Controller are 12 VDC power, USB for command and control, and an AUX connector with a safety interlock and a driver for a warning light.
