Liquid argon (LAr) sampling calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. After detector consolidation during a long shutdown, Run-2 started in 2015 and about 150fb-1 of data at a center-of-mass energy of 13 TeV was recorded. Phase-I detector...

To maximize the physics reach, the LHC plans to increase its instantaneous luminosity to $7.5\times 10^{34}$ cm$^{-2}$ s$^{-1}$, delivering from 3 to 4 ab$^{-1}$ of data at $\sqrt{s}=$14 TeV. In order to cope with this operation condition, the ATLAS detector will require new sets of both front-end and back-end electronics. A new trigger and DAQ system will also be implemented with a...

We explore the possibility of mitigating the effects of out-of-time pileup by developing an alternative scheme for signal amplitude reconstruction that is done online for the CMS Hadron Calorimeter (HCAL). This new scheme makes use of information from bunch crossings preceding the one that would generate an accept decision for the Level-1 Trigger (L1T). The scheme employs basic pulse shape...
