X-ray Source Electronics Set XR40B

XR40B electronics set is used to control the X-ray source RS 40B1.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.


The XR40B set comprises 3 units for full control of the X-ray Source RS40B1.

They are:

- XR40B-EC Emission Controller
- XRHV01-PS High Voltage Power Supply
- XRCB-02 Cooling Box

The XR40B-EC unit controls the emission current of the X-ray source and also the XRHV01-PS high voltage power supply, displaying both, the high voltage and emission current, on a single display. The XR40B-EC displayed emission current is the exact emission current (corrected by the water leakage current of the cooling system). This combination allows very convenient and stable control of the X-ray source. The unit stores information about total anode working time and dissipated power. Communication with cooling box is via fibre optic wire. The XR40B set has both operational and standby modes, guaranteeing the most accurate and stable emission at the start of an experiment. The XRCB02 cooling box delivers water cooling safely and efficiently to the anode and to the housing. It is fully interlocked, monitoring water temperature, pressure and flow, so that the instrument can only operate if fully safe to do so. The cooling box can handle up to two X-ray sources. Autosave function (XR40B-EC unit) for saving your parameters/unit pre-set and applying them automatically after restart.

If any interlock condition is not met, the source cannot be powered on. In addition to these three interlocked safety mechanisms, water leakage current is continuously monitored.
