X-Ray Source Electronics XR40B



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, rather than the emission current derived from the high voltage power supply, which is a sum of the real emission and water leakage current of the cooling system. This combination allows very convenient and stable control of the X-ray source. The XRB40-SET has both operational and standby modes, guaranteeing the most accurate and stable emission at the start of an experiment. The XRCB01 cooling box delivers water cooling safely and efficiently to the anode and to the housing. It is fully interlocked, monitoring water pressure and flow, so that the instrument can only operate if fully safe to do so.

The unit is also fully software controlled and web-enabled so that it can be operated over any network, including the internet. Only one communication interface can be chosen at time of order (please refer to table) but this can be easily changed in the future via simple rear panel plugin connection modules, without ever having to access the internals of the unit.

The XRCB-01 cooling box requires a water feed from a re-circulating chiller for correct operation. In addition to cooling the X-ray source the XRCB-01 may also be used to cool other vacuum system components such as turbo molecular pumps, electron beam evaporators, furnaces etc. Operation of the X-ray source fully protected by water, vacuum, and X-ray tube cover interlocks.

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.


The XR40B-SET comprises 3 units for full control of the x-raysource RS40B1. The XR40B-SET consist of: XR40B- -EC emission controller, XRHV01-PS high voltage power supply and XRCB-01 Cooling Box.


Full dedicated software application or library module.
