NEMO3/SuperNEMO collaboration meeting, Prague The prototype for routine scintillator tests is built and tested. XY table is functioning well with the load of 35 kg. We are prepared to read and analyze data (work is in progress). Prototype will be equipped with 90Sr/90Y source (spectrometer); New testing setup will be built at IEAP CTU based on our experience with the prototype, Bordeaux, Dubna, … Summary and plans / 10
