Includes cylindrical mirror analyzer, USB controller and Windows acquisition and data massage software.
Simple to operate and easy to maintain, the microCMA provides a quantitative surface-sensitive AES Auger Electron Spectroscopy analyzer package that mounts on a 2.75”/ 70 mm CF flange.
For elemental analysis, the microCMA is much more affordable than a standalone XPS system.
The complete AES system includes the cylindrical mirror analyzer (with integrated coaxial electron source), a USB interface controller, and Windows acquisition and data-massage software. It's Auger analysis made easy!
Base package: microCMA analyzer, USB interface controller, preamp with 15 ft (4.6m) cable, data acquisition and massage software, and manual.
Optional accessories: XYZ translator, 9103 USB picoammeter, custom lengths for CMA and preamp cable.

Powered by BiozWhat's Special About the microCMA?
We at RBD Instruments think that the microCMA is the best little AES cylindrical mirror analyzer on the planet.
By utilizing the cylindrical mirror design, the microCMA has the same sensitivity and energy resolution as much larger and more expensive Auger Electron spectrometers.
A CMA accepts electrons at a 42.3° angle (which is the angle where second-order focusing is possible). The CMA Entrance Angle drawing shows that both the 2.75" flange microCMA and the 10.0" 25-120A CMA (used on the PHI 660 system) accept electrons at the 42.3° angle. Since the microCMA has a smaller diameter than the 25-120A, the end of optics-to-sample distance is shorter. But the same electrons are collected whether using the microCMA or the 25-120A.

microCMA Data Compared to Full-Size CMA Data
As shown in the two surveys below, the Auger data taken by the microCMA and 25-120A full-size analyzer are comparable. The surveys are copper samples which were both acquired with 3kV electron beam energy and 300nA of target current.

Theory and Applications
The microCMA is an Auger Spectroscopy cylindrical mirror analyzer designed for the many applications for Auger analysis that do not require AES mapping capability
Those applications include analysis of:
- Thin film elemental composition
- Sample cleanliness
- Metal component thermal oxides
- Quantization of light element surface films
- Surface contamination analysis

Features and Benefits
- Compact: Fits on a 2.75" / 70 mm CF flange yet has a similar signal-to-noise when compared with larger CMAs. The small diameter of the microCMA allows it to fit on existing deposition or analytical chambers.
- Proven Design: The second order focusing of the classical design Cylindrical Mirror Analyzer provides both excellent signa l transmission and energy resolution.
- High Surface Sensitivity: Analyzes the top atomic monolayers of your sample, providing detailed elemental information about surface composition. AES is perfect for elemental surface analysis of thin films and for checking the cleanliness of samples.
- Wide Elemental Range: Detects elements from lithium (Li) and heavier, including light elements which can be difficult to analyze with other techniques.
- East to Use: The integrated 3 kV electron gun, USB control and software interface simplify Auger analysis. The CMapp Auger software provides total control of acquisition parameters and then quantifies the data post-acquisition.

Considerations
- The end-of-optics to sample distance is 4 mm.
- Since the microCMA is so small, the co-axial built-in electron source is limited to 3 kV.
