### Description

The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to determine the effective neutrino mass with a sensitivity of $m_\nu=0.2$ eV/c$^2$ (90% C.L.) using electrons from the tritium beta-decay.
The beta-electrons decaying in the windowless gaseous tritium source (WGTS) are guided adiabatically to the spectrometers, where their energy is analyzed with a present filter width of 2.8 eV.
In order to maintain a stable column density (and therefore a stable luminosity) inside the 10 m long WGTS beam tube, a dedicated closed loop system is installed.
Tritium is pumped out at both ends of the WGTS, purified and re-injected with a throughput of 1.8 mbar$\cdot$l/s into the middle of the WGTS beam tube resulting in a circulation.
In this poster, the results of the first KATRIN tritium measurement campaigns are shown evaluating the stability of the Loops parameters.

### Mini-abstract

The KATRIN Loop system allows the stable circulation of tritium during neutrino mass data taking.
