Endcap Trigger Emulation Xin Wang

2 FEE DSM0 DSM1 DSM2 720 towers 90 trigger patches 12 ‘half’ jet patches 0.3x1 or 0.6x1 2 endcap halves Raw ADC from DAQ file To last DSM board Processing of ADC to L0 trigger decision 6 channels from BARREL, each with 5-bit Esum

Endcap structure: towers -> trigger patches ->half jet patches - >endcap halves

4 FEE HT 6-bit Emulated from ADC Real trigger data Emu-Real difference 3% mismatch

5 FEE TP 6-bit Emu-Real difference Emulated from ADC Real trigger data mismatch

6 BARRELENDCAP Etotal (B+E) Barrel Endcap Etot (E+B) Etot energy in DSM channels  mismatch ~80% ~7% Etot ENERGY calculation from ADC & trig data Trig data ADC emul Trig data ADC emul Trig data ADC emul

7 EmulatedReal data Emu-Real difference Etot BIT calculation from ADC & trig data

8 Conclusion All L0-bits for ENDCAP can be emulated for M-C Code verified against real events for DSM0,1,2 More QA histos developed  ported to online (PPlot) Limitation: works for predefined time stamp (range)
