If we’ll ignore all achievements then the missing answer is why the light yield on small and large tiles is that different. If anyone has ideas - please share. On my part - next week we will make couple small tiles from material used to produce large tiles (we have few large plates) but I am not sure I’ll have time for measurements with cosmic (vacations at UTFSM, lab may be closed). Same can be done at BNL - please discuss.

Who wrote that decree …. why it is about “not to contain” only, without blue/ras - berries it looks like instruction on “how to create void” … 

Otherwise - my summary is trivial: we have an excellent scintillating tiles and we still have a chance to install blends. 

With proper SiPM selection and  dual gain preamps we may have all channels perfectly equalized (there will be only one common to everyone energy scale missing) and ready for the beam even before the cosmic calibration in high bay … But we should still try to do it and test my claim.
