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
