RMC50 Monochromated X-Ray Source

RMC50 monochromated x-ray source

The new RMC50 X-Ray with source monochromator, based around an ellipsoidal quartz crystal, the crystal mirror is installed on a specially designed mechanism with independent retraction, pitch and roll mechanism to ensure precise adjustment of working position. It also features two independent halogen heaters controlled via PID regulator.

The monochromator with a Rowland circle of 500mm diameter for a high x-ray energy resolution has a compact design with differential pumping ports and an optional polymer aluminized window to prevent sputtering.

The x-ray source is based on a completely redesigned dual anode source which is installed on a high precision motion device with three degrees of freedom. The source has two operating modes – high power (up to 600W,) and small spot size for high spatial/energy resolution measurements.

High pressure versions are available:
RMC50 HP5 with working pressure range up to 5mbar
RMC50 HP50 with working pressure range up to 50mbar

X-Ray Source Electronics XR40B

The XR40B-SET comprises 3 units for full control of the X-Ray Source RS40B1: XR40B-EC emission controller, XRHV01-PS high voltage power supply and XRCB-02 Cooling Box. It has the capability to operate up to two x-ray sources.

The XR40B-EC unit controls the emission current of the x-ray source and also the XRHV01-PS high voltage power supply, displaying both 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 unit stores information about summary anode working time and dissipated power. Communication with the cooling box is via fiber optic wire. The XRB40-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 pressure and flow, so that the instrument can only operate if fully safe to do so. The cooling box can accomodate up to two x-ray sources.

The XRCB-02 cooling box requires a water feed from a re-circulating chiller for correct operation. In addition to cooling the x-ray source the XRCB-02 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 is 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.
