Detective Quantum Efficiency of the Timepix4 Hybrid Pixel Detector and its Application to Parallel-Beam Diffraction
Timepix4 achieves zero-frequency DQE above 0.9 at both 100 kV and 200 kV in TEM, with Nyquist DQE above 0.2 at 100 kV but near zero at 200 kV, and detects weak diffraction beyond 75 mrad at 200 kV.
