X-ray Source with Monochromator RMC50
Based on ellipsoidal quartz crystal and operates according to Bragg Law of X-ray diffraction. Crystal mirror has been installed on special designed independent retraction, pitch, roll mechanism to precise adjustment working position and two halogen heaters controlled via PID regulator.
Manufacturer
Prevac
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.
Key Features
- Two anode types (Al/Ag) radiation to be monochromised with one single crystal
- High photon intensity giving a line width of < 0.2 eV
- Excellent energy resolution
- Satellites and ghosts line eliminated
- Reduce background
- Reduce sample distortion
- Crystal temperature stability
- Small spot working mode
Description
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 aluminised window can be installed to prevent from sputtering.
X-ray source based on redesigned dual anode source has been installed on three degrees of motion high precise manipulator. Source has two operate modes – high power up to 600W, and small spot for high spatial/energy resolution measurement.
High pressure versions are available:
RMC50 HP5 with working pressure range up to 5mbar
RMC50 HP50 with working pressure range up to 50mbar
