New “LuSEApher” electron bombardment pixel CMOS camera for bioluminescence studies in ANTARES:
connected to secondary junction box
• S20 Photocathode on vacuum tube:• Focus onto CMOS 400x400 (10 mm) pixel chip operating at
15°C; • Multiplication gain: 3kV accelerating electric field;• Readout: back thinned APS CMOS array • Low noise: dark count: <10-4 g /pixel/frame. • Single-Photon sensitivity• Fast readout: Frame rate = 62-500 Hz• Local disk storage: FIFO readout triggered by event with <ng>> 14
Organisms at -2500m, seen in “LuSEApher” EB pixel camera
RICH2013 Workshop on Cherenkov Detectors, Kanagawa, Japan, December 2-6, 2013
Typ. object size ~ 3mm rms
max extent ~ 10mm X 8 lens

Next Steps• New version of LuSeaPher under construction• Combination of 2 or 3 cameras• Illumination by LEDs of different wavelengths• Stereo view to define distance of object• Foreseen for next version of Secondary JB
(2014-2015)• Active participation of CPPM• Also proposed in European BlueGrowth program

Conclusion• Wide program of interdisciplinary research
around ANTARES• Both hardware and data analysis contributions• To be continued within ANTARES and
MEUST/KM3Net• Near future : New LuSeaPher camera
