EGPS series is the best choice for X or gamma ray measurements in many applications such as Physics or Astrophysics experiments as well as non invasive detection or medical application.
Mirion series EGPS detectors are manufactured using a proprietary technology allowing design for the best strip germanium detectors available worldwide. Mirion uses photolithography techniques – usually employed in microelectronics – to germanium diodes. Thus, all kinds of segmentation patterns are possible (straight or curved strips, pixels, etc.) including double sided thin window segmentation. This reliable technology has been proven since the eighties.
Segmentation offers many benefits:
The segmentation techniques fit with all crystal designs: circular, rectangular, etc. Diodes which are segmented by photolithography allow easier and more accurate 3D localization of interaction points than those obtained with segmented coaxial detectors. This is due to the electrical field characteristics within the detector. Several EGPS detectors may be associated in arrays or may be stacked in a single cryostat, thus offering smaller dead layers to increase of the angular covering (or high energy ray absorption depending on system configuration).
Various similar assemblies of that kind are used for Compton Cameras. EGPS detectors are cooled at liquid nitrogen temperature and may withstand many thermal cycles without any performance degradation. Such characteristics make Mirion EGPS series the best choice for X or gamma ray measurements in many applications such as Physics or Astrophysics experiments as well as non invasive detection or medical application.
