Quality assurance tests of scintillating fibres for the LHCb SciFi Tracker — •Laura Gavardi¹, Johannes Albrecht¹, Christian Joram², Lukas Gruber², and Ana Barbara Rodrigues Cavalcante³ — ¹TU Dortmund — ²European Organization for Nuclear Research (CERN) — ³Centro Brasileiro de Pesquisas Físicas (CBPF)

An upgrade of the LHCb detector is scheduled to take place during the long shutdown LS2 of the LHC in 2019 and 2020. The upgrade of the current downstream tracking system is the SciFi detector, a tracker composed of scintillating fibres read out by silicon photomultipliers. The SciFi project is currently undergoing a transition from the R&D phase to serial production. During this phase 11,000 km of scintillating fibres need to be geometrically refined while their quality is inspected by tests such as measurements of the attenuation length, light yield, diameter, cladding integrity and radiation hardness. In this talk the basic strategy and results of the quality assurance measurements will be presented, focusing on the radiation hardness test.
