PhD Success!

Congratulations to Pablo Arrutia who on 6th March 2024 successfully defended his thesis, titled "Advanced RF techniques for CERN's future slow-extracted beams":

In my research, I worked on the delivery of 400 GeV protons from the CERN Super Proton Synchrotron (SPS) to the experimental users in CERN's North Area. Specifically, I explored a new slow-extraction scheme to provide a one-second proton spill to the recently approved SHiP experiment. SHiP will search for feebly interacting long-lived particles, requiring unprecedented yields achievable only with an increase of protons on target per year and optimised spill quality. My work investigated the use of radio-frequency manipulations to address some of the beam-dynamics challenges arising from such a request . My findings were additionally leveraged to improve the current performance of the SPS and have sparked interest in the medical community, where similar techniques are used in the context of cancer therapy.
