Upgrade of the 25 MW RF Station for the Linear Accelerator LINAC2 at ELSA — •Dennis Proft, Klaus Desch, and Daniel Elsner — Elektronen-Stretcher-Anlage ELSA, Physikalisches Institut, Universität Bonn

At the Electron Stretcher Facility ELSA the first acceleration stage consists of a 3 GHz traveling wave linear accelerator. It was powered by a 25 MW pulsed high power klystron amplifier. After a failure of the focusing solenoid the required output power could not be reached anymore resulting in an inadvertently complete overhaul of the RF station.

The new RF station has successfully been operating since the beginning of 2021. In this contribution I will present the new setup including the new parameter monitoring capabilities as well as the lessons learned in RF engineering as an accelerator physicist.
