EUSO-Super Pressure Balloon
● Pathfinder of Extreme Universe Space Observatory→ EUSO: Measuring UHE Cosmic Rays from space (fluorescence light)
● Super pressure balloon experiment→ Flight altitude 32km→ Expected flight duration: 100 days→ Down-scaled EUSO-like telescope with 36 MAPTMs with 64 channels each
● Balloon went down after 12 days because of leak in balloon

Silicon Photo Multipliers (SiPMs)
● SiPMs have advantages compared to PMTs, especially regarding a space-based experiment
→ Lower operation voltage < 70V→ More lightweight→ More Robust
● Disadvantages : Higher dark count rate, highly temperature dependend sensor
● Testing SiPM capabilities for detecting fluorescence photons with the Silicon Elementary Cell Add-on (SiECA)
● Add-on to the standard EUSO-SPB experiment● Adds 4 SiPM arrays with 64 channels each to the 36 PMTs

Silicon Elementary Cell Add-on (SiECA)
● 4x 64 channel SIPM arrays
● Filter glass glued on the surface of the SiPM arrays
● SiPM read-out via Citiroc ASICs
● Controlled by a Spartan 6 FPGA

Characterizing SiPMs
● SiPMs have to be characterized before usage→ Uniform focal surface
● ‘Single Photon Calibration Stand at KIT’● Characterization stand for photo sensors● Able to generate one-photon pulses to sensor
Conclusion / Outlook
● Successful Measurements with SiECA
● Next project: ● SiECA Version 2● Scintillation particle detector with
SiPM read-out as prototype for IceCube-Gen2 IceTop upgrade
