Rare Probes High Rates n Key observables are rare probes q q n High interaction rate q n either low cross section (e. g. Ω+, d, or J/Ψ) or low branching ratio (e. g. ρ, ω. φ e+e-) design point: 107 Au+Au int/sec @ 11 A Ge. V high count rate detectors significant radiation level for FEE Selective triggers q 27 July 2016 key triggers are ‘tracking triggers’ (decay topology) no hardware trigger, ‘data push’ architecture event selection in software high DAQ bandwidth high computing requirements H 4 F WS Detectors & Accelerators - Walter F. J. Müller, FAIR 3
Detector Electronics n Large R&D effort done on high rate detectors q q n Complemented by high rate electronics q q n typ. shaping times ~30 -80 ns typ. buffer times ~25 -100 μsec and high bandwidth readout q q n TOF: 25 k. Hz/cm 2 TRD: 100 k. Hz/cm 2 about 50. 000 FEE ASICs (hottest have 1 Gbit/sec) use CERN GBTx concentrator ASIC 4. 8 Gbps links Note: FEE and readout must be designed for peak rate good beam time structure is essential !! 27 July 2016 H 4 F WS Detectors & Accelerators - Walter F.
