Abstract: The present invention provides a digital high-resolution detector for detecting X-ray, UV light or charged particles. In various embodiments, the digital detector comprises an array of CMOS or CCD pixels and a layer of conversion material on top of the array designed for converting incident X-ray, UV light or charged particles into photons for CMOS or CCD sensors to capture. The thin and high-resolution detector of the invention is particularly useful for monitoring and aligning beams in, and optimizing system performance of, an apparatus of charged-particle beam e.g. an electron microscope.

Abstract: A rapid and automatic virus imaging and analysis system includes (i) electron optical sub-systems (EOSs), each of which has a large field of view (FOV) and is capable of instant magnification switching for rapidly scanning a virus sample; (ii) sample management sub-systems (SMSs), each of which automatically loads virus samples into one of the EOSs for virus sample scanning and then unloads the virus samples from the EOS after the virus sample scanning is completed; (iii) virus detection and classification sub-systems (VDCSs), each of which automatically detects and classifies a virus based on images from the EOS virus sample scanning; and (iv) a cloud-based collaboration sub-system for analyzing the virus sample scanning images, storing images from the EOS virus sample scanning, and storing and analyzing machine data associated with the EOSs, the SMSs, and the VDCSs.
