TI - High Power RF Transmission Lines of the Light Proton Therapy Linac J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - The LIGHT (Linac for Image-Guided Hadron Therapy) machine is designed to accelerate a proton beam up to 230 MeV to treat deep seated tumours. The machine consists of three different kinds of accelerators: RFQ (Radio-Frequency Quadrupole), SCDTL (Side Coupled Drift Tube Linac) and CCL (Coupled Cavity Linac). These accelerating structures are fed with RF power at 750 MHz (RFQ) and 3 GHz (SCDTLs and CCLs). This power is delivered to the accelerating structure via the high power RF transmission network (RF network). In addition, the RF network needs to offer other functionalities, like protection of the high RF power feeding stations, power splitting, phase and amplitude control and monitoring. The maximum power handling of the RF network corresponds to a peak RF power of 8 MW and an average RF power of 9 kW. It functions either in Ultra-High Vacuum (UHV) conditions at an ultimate operating pressure of 10⁻⁷ mbar, or under pressurized gas. The above listed requirements involve different challenges. In this contribution we exhibit the main aspects to be considered based on AVO experience during the commissioning of the RF network units.
