Investigation of Electronic Crosstalk in the Optical Modules of the Pacific Ocean Neutrino Experiment — •Lars von der Werth for the P-ONE collaboration — Technische Universität München

The Pacific Ocean Neutrino Experiment (P-ONE) is a proposed cubic-kilometer*scale neutrino detector to be deployed in the Pacific Ocean. Its fundamental detection units are the P-ONE optical modules (P-OMs), each housing 16 photomultiplier tubes (PMTs) to record Cherenkov light emitted by secondary particles produced in high-energy neutrino interactions. Each P-OM includes a trigger system that performs an initial selection of relevant signals. A detailed understanding of the internal electronic crosstalk is essential for reliable triggering. To characterize these effects, electromagnetic interference (EMI) measurements help identify the dominant noise sources and investigate the pathways through which these couple into the PMT signal. Further, we present how different grounding schemes, cabling configurations, and shielding strategies affect the crosstalk level observed in the different PMT positions within the P-OM.
