Abstract

The KArlsruhe TRItium Neutrino (KATRIN) experiment will measure the mass of the neutrino with a sensitivity of 0.2 eV (90 % CL). The Forward Beam Monitor (FBM) is a monitoring system which comprises of a complex mechanical setup capable of inserting a detector board into the KATRIN beamline at the end of the source and transport section. The detector board contains a Hall sensor, a temperature gauge, and two PIN diodes which can detect electrons from the source with a precision of 0.1 % in less than a minute within an electron flux density of 106 s−1mm−2.

Highlights

  • The mass of the neutrino is obtained by KArlsruhe TRItium Neutrino (KATRIN) by observing the β-electron spectrum from the decay of tritium in the Windowless Gaseous Tritium Source (WGTS)
