Recently, a stability of Data Acquisition System (DAQ) has become a vital precondition for a successful data taking in high energy physics experiments. The intelligent, FPGA-based Data Acquisition System (iFDAQ) of theCOMPASS experiment at CERN is designed to be able to readout data at the maximum rate of the experiment and runsin a mode without any stops.

Using FPGA technology for event building tasks in high-energy physics experiments reduces costs and increases reliability of DAQ systems. In 2014, the COMPASS experiment at the Super Proton Synchrotron at CERN commissioned a novel, intelligent, FPGA-based DAQ in which event building is entirely performed by FPGA cards. [...]

Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV
/ CMS Collaboration
Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are presented. The corrections as a function of pseudorapidity $\eta$ and transverse momentum $p_{\mathrm{T}}$ are extracted from data and simulated events combining several channels and methods. [...]
