Description
The KArlsruhe TRItium Neutrino experiment (KATRIN) will investigate the spectral shape of beta-decay electrons close to their kinematic endpoint in order to determine the neutrino rest mass in a model-independent method with an unprecedented sensitivity of 0.2 eV/c^2.
For this purpose KATRIN makes use of a molecular gaseous tritium source, a transport section with differential and cryogenic pumps, two electrostatic spectrometers with magnetic adiabatic collimation (MAC-E filter) and a segmented silicon detector.
Apart from detector DAQ a large number of heterogeneously distributed sensors has to be constantly monitored by a mixed PSC7 and Fieldpoint / Labview based slow-control system. The system has to maintain highly stable operating conditions over several years in order to reach the challenging sensitivity goal. As the experiment approaches the commissioning phase, the KATRIN analysis framework is currently under development. The server-side data processing will be handled by a central C++ web service, employing an object-relational mapping (ORM) database layer, XML data binding and an intuitive remote procedure call (RPC) interface to the actual client-side, ROOT based analysis applications.
