  • Better stopping power than implanted silicon PIPS  detectors: up to 3 MeV Betas, 30 MeV protons, 140 MeV Alphas. More if detectors are stacked
  • Designs for LN2 cooled applications like conversion electron spectroscopy
  • As an option:
    • Thin back contact available (transmission option) for the dE/dx measurement or stack arrangement with connector on the side
    • Special dimensions, shapes, connectors
    • Segmentation: pixels or strip / single or double sided

SiLi Detector X-ray Silicon Lithium Detector for X-ray Spectroscopy

Silicon Lithium X-Ray Detectors are the heart of solid state x-ray spectroscopy systems. These detectors, which are p-i-n devices formed by lithium compensation or drifting of p-type silicon, are the result of some of the most carefully controlled manufacturing processes in existence.
