  3. 1st Flight Mission Objectives • To validate the IR camera mission concept • To obtain real data with ULIS UL 04171 micro bolometer IR camera • To assess the wavelength bands and filters selection 8.55 m band IR camera funding achieved to be on the 1st flight and test the 8.55 m filter band for the IR camera/JEM-EUSO baseline • To validate and optimize Temperature Retrieval Algorithms • To validate and optimize Stereo Vision Technique • To validate and assess part of Calibration Strategy (Shutter)

  4. IR Camera Detector (UL 04171) Technology-Si Manufacturer: ULIS Proximity electronics and Signal digitalization Resolution: 640x480-25m, 16bits NETD < 120mK Frame Rate: 0,5 FPS Power consumption: <300 mW (without TEC)

  5. IR Camera • Operational Bands • Band 1: • CWL: 10.80 (+0, -0.2) m • FWHM: 0.85 ± 0.1  m • Transmittance > 80; • Transmittance Rejection Band: 7 to 10.0 m < 0.01; 11.4 to 20 m < 0.01 • Band 2: • CWL: 8.55 (+ 0.2, -0) m • FWHM: 0.85 ± 0.1 m • Transmittance > 80 • Transmittance Rejection Band: 7 to 11.3 m < 0.01; 12.7 to 20 m < 0.01 FOV≈12º

  10. Mechanical Configuration • EUSO IR Camera accomodation • Located on the external side of the • Gondola • Totally isolated • Autonomous batteries • EUSO IR Camera mechanical booth • Withstand environmental conditions • Water proof • Passive (alluminium panel radiator) • and active thermal control (heater) EUSO Balloon Gondola

  11. Mechanical Configuration

  12. Mechanical Configuration Complete system weight: 27.6 kg 15g (vertical) scenarioWeight @ 15g = 27.6x15 = 414 kg.6x3 screw option: Weight supported per screw: 414/18 = 23 Kg per screw 5x3 screw option: Weight supported per screw: 414/15 = 27.6 Kg per screw

  13. Thermal Configuration Radiator: emissivity 0,15 Housing: emissivity 0,7 15mm thick Alu Internal dissipation: -Camera 7.8W -CPU 5W -DCDC 5W -Other 2W Housing-radiator: 300W/m2.K Heat sinks: -Air @ -80ºC (0.0202 W/mK) -Space@-270ºC (View factors computed in ESARAD) IR Earth load: 260W/m2 Albedo: 0,12

  14. Thermal Configuration • Cold Case: • Operational, steadystate • Nightobservation • Temperatures: • Camera 22ºC • CPU 14ºC • DCDC 14ºC

  15. Thermal Configuration • Hot Case: • Non operational, steadystate • No observation This thermal case includes solar fluxes

  16. IR Camera Battery Pack technical specifications

  17. IR CAMERA Budgets • Preliminary estimation has been done and reported: • SIZE 235 x 240 x 270 mm3 • MASS 27.6 Kg • POWER 30W • Functional Requirements • The EUSO Balloon IR camera subsystem will be reusable for all the balloon campaign opportunities.
