Thermal oscillator

A thermal oscillator was a form of control mechanism present on Starkiller Base superweapon. Its function was to prevent the planet from destabilization as it collected and stored vast amounts of solar energy to fire on distant star systems.

History
One large thermal oscillator was located in District 47 of Starkiller Base, where an attack was led by the Resistance to disable or destroy it before the weapon could fire on D'Qar. The attack was successful, preventing the firing of the superweapon and the subsequent destabilization of the planet.
