3. NEMO3/SuperNEMO collaboration meeting, Prague
Motivation
Routine tests of big amount of scintillators should be shared among several laboratories
Prague will participate in the tests
Details of a testing procedure are not decided yet
Some setups already exist (Bordeaux, Dubna, ...)
Proposal of F.Piquemal for „multibox setup“
Plan – setup in IEAP CTU Prague
Prototype setup in IPNP CU Prague

Summary and plans
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, …
