DECTRIS ARINA Ultra-Fast 4D STEM Detector

The DECTRIS ARINA is an ultra-fast 4D STEM detector that does not trade off on sensitivity or dynamic range.

The DECTRIS ARINA retractable, electron-counting detector is designed to handle 4D STEM applications. It features a new ASIC and combines an extreme speed of up to 120,000 frames per second with a noise-free readout and a high dynamic range. Thisallowssuperior-quality data acquisition at the conventional speed of a traditional STEM measurement.

Owing to DECTRIS’ hybrid-pixel technology, ARINA can utilize various sensor materials and runs optimally in the entire energy range from 30 to 300 keV.

DECTRIS ARINA is ideal for a wide range of 4D STEM applications with dwell times lower than 10 μs, spanning from crystalline phases and orientation mapping to ptychography, including versatile STEM image reconstruction using virtual detectors.

Flexible: Comprising silicon (Si) or high-Z sensor materials, DECTRIS ARINA encompasses an extensive range of energies from 30 to 300 keV.

Rapid and sensitive: The DECTRIS ARINA can count every single electron—up to 10 pA/pixel even at a frame rate of 120 kHz.

Empowering: The DECTRIS team, comprising engineers and scientists, is ready to assist users in obtaining the maximum from their setup.
