Active damper of magnetically suspended pellet for laser fusion scheme

摘要

In laser fusion experiments, the presence of a supporting stalk affects irradiation uniformity. The magnetic suspension system (MSS) realizes a non-contact technique of stably supporting pellets by the magnetic force. The small mechanical vibration of the system, when it exists, swings the magnetically suspended pellet (MSP). In order to damp the swing motion, we introduce the active damper.
