Description 

The CANBERRA ESLX-S detectors are manufactured using a proprietary technology allowing design of the best segmented silicon detectors available worldwide.

CANBERRA has applied the photolithography techniques -usually employed in microelectronics- to Si(Li) diodes. Thus, all kinds of segmentation patterns are possible (straight or curved strips, pixels, etc.). This technology has been proven for 5 years.

CANBERRA also offers a proprietary double sided thin window segmentation.

Segmentation offers many advantages:
Suppression of dead zones between consecutive strips
Small pitch: down to 300 µm
Good behaviour at high count rates (up to 1 million pulses per second)
2-sided photolithography capability, with pitchs up to 300 µm
Excellent FWHM resolution: typically 150 eV at 5.9 keV on cooled devices for X-ray measurements
No measurable crosstalk.

The segmentation techniques fit with all cristal designs: circular, rectangular, etc...

Several ESLX-S detectors may be associated in arrays to increase angular covering or may be stacked in a unique cryostat, thus offering high energy X-ray absorption or imaging capabilities (gamma cameras).

ESLX-S detectors are cooled at liquid nitrogen temperature and withstand many thermal cycles.

Such characteristics make ESLX-S series the best choice for Xray measurements in many applications such as Physics experiments as well as non invasive detection.
Applications
PIXE (microprobes)
Synchrotron (EXAFS, medical beam lines)
Nuclear Physics
Non destructive control
Radiography
