Overview PANDA Experiment at FAIR

High Rates σ ~ 55 mb 3x107 interactions/s

Micro Vertexing Charged particle ID

– (e±,μ±,π±,p,…)

Tracking /TPC EM. Calorimetry

(γ,π0,η)

Forward capabilities (leading particles)

Sophisticated event selection

Requirements for PANDA TDAQ Interaction rates up to 30MHz

typical event sizes 4 - 20 kB.

data rates after front end preprocessing: 40GB/s - 200 GB/s

high flexibility and selectivity

Solution: continuously sampling data

acquisition No „hardware triggers“ Precision clock distribution system Digital signal processing at FrontEnd

level
