ASI's Cheetah is a hybrid pixel detector suitable for electron microscope applications. The sensitivity and speed of Cheetah offers unprecedented possibilities for electron diffraction, imaging and tomography. Scintillated detectors do not have the signal to noise ratio's that can be obtained with the Cheetah. Other direct electron cameras lack the dynamic range the Cheetah has and are too beam sensitive to be used for diffraction experiments. The Cheetah's high speed makes it ideal for looking at dynamic processes and catching fast fading signals.
