August 2023 microscope status update

We performed another benchmarking on August 17 for the Titan Krios. At magnification 130kx, we collected 717 exposures and extracted 209021 particles. Cryosparc gives a resolution of 1.93A. The pixel size is around 0.93A. We believe the Nyquist is reached. At magnification 165kx, we collected 992 exposures and extracted 108962 particles. Cryosparc gives a resolution of 2.01A. The pixel size…
