  1. LNF - Beam Test Facility Sept. 29 – Oct. 04 Characterization of LAZIO Detectors Low Altitude Zone Ionizing Observatory

  2. Outline • Purposes of the Beam Test • Beam Characteristics • Instrumental Setup • Mechanics • Electronics • Data Analysis and Results • Future Purposes and Conclusions Low Altitude Zone Ionizing Observatory

  3. Purposes • Instruments: • Scintillator Detectors • Light Guide • Photo Multipliers • LabView based Acquisition System • Measures: • Detector Resolution • Light Counting Attenuation vs Distance • Relative Detector Efficiency • Normalizzation to the BTF Calorimeter Countings Low Altitude Zone Ionizing Observatory

  4. Beam Characteristics • 500MeV electrons • Repetition Rate 50 Hz • Pulse Duration 1-10 ns • Current/pulse 1 to 8 particles • σXY~2mm • Max Electronic Rate: 1KHz Low Altitude Zone Ionizing Observatory

  5. Setup - Mechanics Beam line BTF Calorimeter Scintillator Beam Trigger Mover Low Altitude Zone Ionizing Observatory

  6. Scintillator Beam Calorimeter Scint. Acquisition System Calorim. Setup - Electronics Beam Trigger 860 mV HV Power Supply 5:1 Attenuator 15 V CAMAC CAMAC Power Supply DAQ Fanin Fanout Delay units 12 bit ADC CAMAC Discriminator Scaler Ext.TRG Beam Trigger Low Altitude Zone Ionizing Observatory

  7. Calorimeter Informations on Beam Energy distribution Data analysis - First View • Scintillator Data extraction by BTF calorimeter informations Low Altitude Zone Ionizing Observatory

  8. Filtered Data: Selection of the single electron contribution in the BTF Calo data Data analysis - Investigations Obtained Data: • Single electron contribution in the Scintillator data • Instrumental Resolution Low Altitude Zone Ionizing Observatory

  9. 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 Low Altitude Zone Ionizing Observatory

  10. 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 Low Altitude Zone Ionizing Observatory
