Scintillator Data extraction by BTF calorimeter informations
Sept. 29 – Oct. 04 Low Altitude Zone Ionizing Observatory
Data analysis - Investigations
Filtered Data: Selection of the single electron
contribution in the BTF Calo data
Obtained Data: Single electron contribution in the
Scintillator data Instrumental Resolution

Results
Preliminary results: Linear behaviour of Light
Counting Attenuation vs distance (beam spot – light guide)
Next analysis: Detector Efficiency relative
to the BTF Calorimeter countings
Sept. 29 – Oct. 04 Low Altitude Zone Ionizing Observatory
Conclusions and Future
The BTF Calorimeter is a powerful tool in the Data investigation
The collected Light follow a linear behaviour as expected
Good understanding of BTF allow us to:• Realize a proper mechanical structure for the future test on
the flight model
• Find out the best configuration for the test with Front End and Read Out electronics
