X-Ray Detectors for Synchrotron Applications

Operating in fluorescence mode, Discrete or Monolithic Germanium Array Detectors provide excellent resolution with high throughput rates - exactly what is demanded in Extended X-Ray Absorption Fine Structure experiments.

Discrete Array Detectors (with individual detector elements)
  • 2 to 32 Elements
  • LEGe (3 keV and up) or Ultra-LEGe (1kev and up) elements
  • Low crosstalk
  • High resolution with short pulse processing times
  • Excellent peak/background without collimation
  • Good performance from 1keV and up with Ultra-LEGe elements and thin Be windows
  • Windowless cryostats available for very low X-ray energies
Monolithic Array Detectors (pixels in a single germanium or SiLi substrate)
  • 3 to 100 pixels
  • Energy range- 3 keV and up
  • High packing density
  • Good resolution with moderate pulse processing times (1/2 µs Gaussian)
  • Good peak/background with optional internal collimator to reduce charge sharing between pixels
  • Synchronous preamplifier reset with built-in electronics
Single element X-Ray Detectors
  • Low Energy Germanium (LEGe) Detectors for 3 keV and up
  • Ultra Low-Energy Germanium Detectors for 1 keV and up
  • Lithium-Drifted Silicon (SiLi) Detectors for 1-25 keV with or without segmentation
  • X-PIPS™ Detectors for 1-20 keV (Miniature Peltier-Cooled Devices)
Photodiodes for beam alignment
  • Low dark current
  • Fast read-out
  • Used in photovoltaic or biased mode
  • No optical window

In the mid 1980s the first 13 Element discrete Ge Array Detector came to be and soon we had orders for similar detectors from SSRL, Daresbury and many other light sources in the US, Europe, and Japan. Some users in the Synchrotron Community were not completely satisfied with the largest of the Canberra Discrete Array Detectors (32 element) demanding even more channels. In 1998, Dr. Oyanagi, from Spring 8 in Japan ordered the first 100 monolithic Pixel Detector. Since then Canberra has produced several more 100 Pixel Detectors as well as detectors with fewer Pixels, 36 being a popular size. CANBERRA's product offering today contains both monolithic array detectors having 3 up to 100 pixels or discrete array detectors of up to 32 channels.

The new Self Adaptive Feature Enabling (SAFE™) allows drastic improvements for high count rate capability. Automatic mode with presets can be performed at factory or in manual mode where user can choose given pixels impinged by diffraction through an USB interface & PC software. This new interface allows remote read out of detector parameters: remote service maintenance.
