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.
