Add a Complete Auger System to Your Vacuum Chamber
Simple to operate and easy to maintain, the microCMA provides a complete quantitative surface sensitive elemental Auger Electron (AES) 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 gun), 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.

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
Overview Video
Features
- Compact: Fits on a 2.75" / 70 mm CF flange (min. 1.52" / 38.6 mm I.D. tube). It is now possible to build an Auger Spectroscopy system with just a T and a small ion pump!
- Proven Design: The second order focusing of the Cylindrical Mirror Analyzer provides both good transmission and resolution.
- Easy to Use:The USB control and data-massage Auger software interface is simple to use and makes Auger analysis easy.
- Powerful: Auger Spectroscopy (AES) is a powerful surface sensitive technique that provides you with quantitative information on the first few monolayers of your sample.
Benefits
- The small diameter of the microCMA allows it to fit on existing deposition or analytical chambers.
- Because the microCMA is based on the classic cylindrical mirror analyzer design, it has a similar signal-to-noise when compared with larger CMAs. Basically, the microCMA collects the same electrons as larger CMAs do; it just collects the electrons closer to the sample.
- Integrated 3 kV electron gun simplifies the CMA-to-sample alignment.
- Electron gun has automated features such as warm up and conditioning.
- The microCMA is perfect for elemental surface analysis of thin films and for checking the cleanliness of samples
- 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 gun is limited to 3 kV.
