Status of the KATRIN Experiment — •Fabian Harms for the KATRIN collaboration — Karlsruhe Institute of Technology (KIT), Institute for Nuclear Physics (IKP)
The KArlsruhe TRItium Neutrino (KATRIN) Experiment is a large-scale experiment for the model independent determination of the effective mass of the electron-antineutrino with a sensitivity of 200 meV/c2 (90% C.L.). It investigates tritium β-decay close to the kinematic endpoint of the energy spectrum with a high-resolution electrostatic spectrometer (ΔE = 0.93 eV at 18.6 keV).
The KATRIN experimental setup consists of a high luminosity windowless gaseous tritium source (WGTS), a magnetic electron transport system with differential and cryogenic pumping for tritium retention, a series of two electrostatic spectrometers (pre-spectrometer and main spectrometer) for energy analysis, and a detector system based on a segmented silicon PIN diode detector for efficient counting of transmitted β-electrons.
With all main components on site at KIT, the experiment celebrated ’FirstLight’ on 14th October 2016 by successfully transmitting electrons through the 70-m long experimental setup. The talk will present the current status of the experiment and give an overview on the results of the recent FirstLight measurement campaign.
