• Smaller Mie Scattering– ~20%

• Low Cloud (2~3km) in night– Most of the showers reaches

the maximum above the cloud

• Smaller Absorption (loss)– ~ 0.3, and uncertainty < 0.05– Large absorption/uncertainty

(loss) X 10 ~100 for ground fluorescent observatory

• Well determined Distance to a Shower – Observation altitude : ~400km– Shower altitude : ~10km

Looking Down from Space is much better than Looking Up from the Ground; also duty cycle 20-25% instead of 13%.

Fluorescence yield measurement

(APC & LAL & Madrid)

Goal: 5% precision

PHIL electron accelerator

Measurement at atmospheric pressure only with a 5% precision: "Absolute measurement of the nitrogen fluorescence yield in air between 300 and 430 nm" G. Lefeuvre et al. NIM A 578 (2007)78

Page 32: JEM-EUSO:Current status and perspectives Philippe Gorodetzky APC-Paris 7 — CNRS/Univ for the JEM-EUSO Collaboration Philippe Gorodetzky APC-Paris 7 — CNRS/Univ

Front-end ASIC (LAL)

- Shower measurement: single electron mode. Best results: photon counting (existed in "old" MAROC chip at LAL)

- Most other measurements involve more light: counting saturates. Pulse charge integration (existed in "old" japanese chip)

- Best of both worlds: the two circuits on the same ASIC at LAL

- Power reduced to 0.5 mW / pixel (175 W total)

Page 33: JEM-EUSO:Current status and perspectives Philippe Gorodetzky APC-Paris 7 — CNRS/Univ for the JEM-EUSO Collaboration Philippe Gorodetzky APC-Paris 7 — CNRS/Univ

Success Criteria

• Arrival direction– < 2 degrees

• Energy resolution– < 30%

• Hadron/Photon/neutrino :– ΔXmax < 120 g / cm2
