I guess you mean "acquisition"? Is LHC L1 trigger not hardware based? That was always my understanding, or has it evolved in recent years?

- elashri 3y agoYes, stupid iPhone autocorrecting words. LHC experiments (CMS,ATLAS, LHCb and Alice -others) up until run 3 (started last year) used all level one hardware based trigger (FPGAs). But LHCb with run 3 is doing all the triggering on the software side [1] And yes this allows Real time analysis (RTA) to be done. Well this is quite something that was new. But also to be honest is easier to do with LHCb than its big siblings ATLAS and CMS because of higher pile-up and instantaneous luminosity.
