Overview of the CheeTah T3 EELS

CheeTah T3 detectors are event-driven, time-resolved hybrid pixel detectors with monolithic sensors. The 1.56 nanosecond time resolution enables the end user to perform experiments where time resolution is key, and is particularly advantageous for short dwell time STEM applications.

Specifications

  • Direct electron counting detector for event-driven EELS
  • Time resolution of 1.56 nanoseconds
  • Real-time data preview
  • Optimised sensor for 200 and 300 kV microscopes
  • 1024 x 256 pixels (1 x 4) monolithic sensor

Features of the CheeTah T3 EELS

Compact design enabling integration to a wide range of energy filters
