TileCal, the central hadronic calorimeter of the ATLAS detector is composed of plastic scintillators interleaved by iron plates, and wavelength shifting optical fibres. The optical properties of these components are known to suffer from natural ageing and degrade due to exposure to radiation. The calorimeter was designed for 10 years of LHC operating at the design luminosity of...
Two neutral particle detectors, Zero Degree Calorimeters (ZDCs) at the LHC-CMS experiment, cover the $|\eta| > 8.5$ region. The ZDCs are Cherenkov calorimeters that use tungsten as the absorber and quartz clad quartz fibers as the active medium. They have a five element electromagnetic section followed by a hadronic section divided into four depth segments. For the 2016 pPb run, the ZDCs were...
The ALICE experiment at the LHC is dedicated to the study of the quark-gluon plasma formed in high-energy nuclear collisions. The ALICE electromagnetic calorimeter system, which includes the EMCAL/DCAL lead-scintillator sampling calorimeters and the PHOS high-granularity lead-tungstate crystal calorimeter, provides measurements and triggering on hard probes of the quark-gluon plasma such as ...
The Zero Degree Calorimeters of the ALICE experiment were designed with the twofold purpose of both estimating the centrality in heavy ion collisions by measuring the energy carried away by the spectator nucleons and of measuring the luminosity delivered to the experiment exploiting the high cross sections for neutron emission from electromagnetic dissociation process. The measurement of...
