Low energy (1017 – 1018.5 eV) enhancement for the Pierre Auger Observatory,

Detection of muon component 3m underground

80 MHz prototype – 4 segments

Zbigniew Szadkowski, University of Łódź

slide3

4th generation of the Front-End CycloneIII™ FPGA

320 MHz prototype with NIOS - 2 segments only

Higher sampling underground: 80 -> 320 MHz

Higher sampling on the surface: 40 -> 100 MHz

Two segments only: higher reliability

NIOS processors both underground and on the surface: no problem of obsolescence

T1 – trigger

+ FEBTS

LVDS communication between NIOS
