X-ray Monochromator Source for XPS, ESCA

The New RMC 24 X-Ray Monochromator for

Monochromized X-Ray Photoelectron Spectroscopy

High Intensity X-Ray Source
Very High Energy Resolution
New Monochromatic Aberration Correction
New Focussing Optics with Dual-Focussing Lens for Photon Point Exitation

The RMC 24 is a new, high intensity Monochromized X-ray Source optimized for MXPS Experiments. Design of the X-ray Source, Radiation Mirror and monochromator housing guarantees maximum X-ray intensity at a small spot. A specially configured X-Ray Window allows protection of the crystal in case of accident.
