Inductive adders for replacing thyratron based modulators at CERN

Line-type modulators, for example pulse forming lines and pulse forming networks, which use thyratron switches, are currently used in many pulse power systems at CERN. Solid-state modulators implemented with inductive adder technology could replace thyratron based designs in many applications and potentially improve dynamic range, maintainability and reliability of the systems. This paper will discuss the application of an inductive adder for the pulse power modulator of both a future circular collider and as an upgrade to an existing, 45 year old, kicker system.
