Performance results of the trigger logic implemented in EUSO-SPB

Abstract EUSO-SPB (Extreme Universe Space Observatory - Super Pressure Balloon) was the first mission of the JEM-EUSO program which implemented the First Level Trigger (FLT) logic to detect Ultra-High Energy Cosmic Rays (UHECRs) following the scheme developed for the JEM-EUSO mission. Experimental results matched the expected behavior of the logic and satisfied the requirements conceived for the FLT. The sensitivity of EUSO-SPB to the detection of UHECRs was established.
