• Direct neutrino mass determination
• KATRIN
• Background reduction
• Screening wire electrode system

Aims. KATRIN is a neutrino mass experiment based on the kinematics of tritium beta-decay. This work presents the methods employed at KATRIN to reduce the spectrometer-related background.
Methods. The electrode system of the main spectrometer includes a modular double-layer wire grid for electrostatic screening of background. The key features of the wire electrode and the underlying design criteria of the optimisation procedure are described.
Status. Fabrication of the wire electrode modules is completed and installation into the KATRIN main spectrometer has started.
