Status of the tritium-source related parts of KATRIN — •Michael Sturm for the KATRIN collaboration — Karlsruher Institit für Technologie (KIT)
The KArlsruhe Tritium Neutrino Experiment (KATRIN) aims for the direct model-independent neutrino mass measurement with a sensitivity of mνe< 200 meV (90% C.L.). While the commissioning of the high resolution MAC-E Filter has already started, some of the tritium related components are still in the finishing stage at the manufacturers. We give a status report on all source and transport components of KATRIN as well as all related tritium processing and analytic intruments at the Tritium Laboratory Karlsruhe. Additionally we describe the improvements in simulations and our program to characterize the components in advance of tritium data taking. This is of special importance as the statistical and systematic uncertainties of the mνe measurement are closely related to the performance and stability of the windowless gaseous tritium source - as well to the functionality of the transport section, which has to reduce the tritium ow by 14 orders of magnitude in order to avoid backgrounds and to the performance of monitoring systems which are able to detect changes in the source parameters down to a precision of 0.1%.
