Introduction Muon data results BTF Frascati test APSS Trento test Conclusions
Performed beam tests
The LIMADOU-HEPD has been tested to fully char-acterize its performances:
I Tests with cosmic muons (multiple runs.Different locations);
I Tests with electrons (October, 2016. BTFFrascati IT);
I Tests with protons (November 2016, APSSTrento IT).
The results of the tests allow the collaboration to fullycharacterize the detector performances, with a particu-lar attention to the tracker and the upper calorimeter.In this presentation I will show the main results aboutthe detector performance.

I Electrons above 30 MeV escape the upper caloand are stopped by the lyso crystals;
I The obtained data are used to calibrate inenergy the calo response;
I Equalization for trigger bars and calo plane havebeen calculated and implemented inrecontruction software;
I The number of peaks in energy distribution aredue to events with high multiplicity.

Conclusions
I The pre-launch tests allow a full characterizationof the detectors;
I For the tracker:I The track reconstruction capabilities have been
tested and validated;I The energy release has been characterized to
perform particle identification.
I For the calo:I We used the data from the test beam for energy
calibration;I All the sub-section of the calo have been fully
characterized.
I We are now ready for the launch and waiting forthe real work to begin!
