Mini-X2 X-Ray Tube System

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 optimized 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. 

Several different options are available: 

Max HV50kV70kV
Max Power4W10W10W
AnodeAg, Au, Rh, or WAg, Au, Rh, or WAu, Rh, or W

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.

 The Mini-X2 is a replacement for Amptek’s previous Mini-X product family.  The X-ray Tube Module is similar to the previous Mini-X-OEM. 

The Controller has significantly improved control features, including software configurability and faster control and readback.  It utilizes a completely different software interface, based upon the FW6 protocol used with Amptek’s digital pulse processors.

Convenient  threads for attaching collimators or filters are available on all 50kV models.
