Abstract: One modified source-conversion unit and one method to reduce the Coulomb Effect in a multi-beam apparatus are proposed. In the modified source-conversion unit, the aberration-compensation function is carried out after the image-forming function has changed each beamlet to be on-axis locally, and therefore avoids undesired aberrations due to the beamlet tilting/shifting. A Coulomb-effect-reduction means with plural Coulomb-effect-reduction openings is placed close to the single electron source of the apparatus and therefore the electrons not in use can be cut off as early as possible.

Abstract: A consensus method and system in a consortium blockchain is provided. An example method includes, when a first consensus node in a consensus network of the consortium blockchain does not complete a consensus operation on target data on which a consensus is to be reached within a predetermined time period, the first consensus node broadcasts a ViewChange message in the consensus network based on a P set and a Q set constructed from an ECHO message. For a received ViewChange message, a second consensus node sends a ViewChangeACK message corresponding to the received ViewChange message to a second consensus primary node. When the second consensus primary node receives N?f?2 ViewChangeACK messages from consensus nodes, the second consensus primary node obtains identical P sets and a identical Q sets in the received ViewChange message. The second consensus primary node makes a view change decision based on the received ViewChange message.
