    Abstract: Apparatuses and systems for damping vibration of a vacuum vessel mounted with a pump include a pump body and a damping element coupled to the pump body, wherein the pump body and the damping element form a mass-based damper, and wherein the pump body forms a mass component of the mass-based damper; and the damping element forms a damping component of the mass-based damper. The apparatuses and systems also include a pump body configured to be secured to a column of a charged-particle inspection apparatus, a sensor coupled to the pump body, an actuator coupled to the pump body, and a circuitry communicatively coupled to the sensor and the actuator for receiving motion data indicative of a vibration of the column; determining a damping based on the motion data; and actuate the actuator to react to the vibration of the column in accordance with the damping.

    Abstract: Embodiments consistent with the disclosure herein include methods for image enhancement for a multi-beam charged-particle inspection system. Systems and methods consistent with the present disclosure include analyzing signal information representative of first and second images, wherein the first image is associated with a first beam of a set of beams and the second image is associated with a second beam of the set of beams; detecting, based on the analysis, disturbances in positioning of the first and second beams in relation to a sample; obtaining an image of the sample using the signal information of the first and second beams; and correcting the image of the sample using the identified disturbances.
