Configure ZDC Trigger Simulation to simulate new UCC triggers, plus now perform simulation over run3 data directly from ADC values
The ATLAS ZDC Trigger simulation was configured last year with the purpose of estimating Run3 ZDC L1 rates using Run2 data, see ATR-26821.
Now that we have Run3 HI data, we have configured the ZDC Trigger simulation to be much more precise, using the Flash ADC values recorded in the ZDC to emulate the trigger.
Furthermore, this year the HI menu will include new alternative ZDC triggers to select on Ultra Central Collisions (UCCs), see ATR-29719. We have included these new ALT ZDC triggers in the simulation in order to estimate the rates for these items, in the coming PbPb data taking.
No functional changes to the previous Trigger Simulation (i.e. TrigT1ZDC), added Algorithm TrigT1Run3ZDC which includes new functionality. Currently uploading LUT for the new Trigger simulation in a common area, see ATLASG-2538.
