Title: Calorimetry in ALICE at LHC
Abstract content ALICE at the Large Hadron Collider (LHC) is the dedicated experiment focused on heavy ion collisions at LHC, to study a de-confined matter of quarks and gluons, called Quark Gluon Plasma (QGP). Among the sub-detector systems in AILCE, there are two types of calorimetry in the central barrel. One is EMCal (Lead-Scintillator, a sampling electromagnetic calorimeter with a WLS fiber and APD readout), having a wide geometrical acceptance to measure jets, and photons and neutral mesons with a moderate energy resolution. Another type of calorimeter is PHOS (PHOton Spectrometer), PbWO$_4$ crystal with APD readout for high granularity and higher precision energy measurement for photons.
In this talk, we review those detectors performance in ALICE, and show ongoing upgrade projects in calorimetry, such as 1) DCAL (Di-jet Calorimeter), an extension of EMCal coverage to measure back-to-back jets, 2) PHOS upgrade to achieve 50 kHz readout speed in minimum bias Lead-Lead collisions at LHC-Run-2. Furthermore, we present an upgrade proposal for the forward direction calorimetry, FOCAL, to measure direct photons in $\eta = 3.3 - 5.3$, by using a nobel technology of silicon photo-diodes with absorbers based electromagnetic calorimeter for photons, together with a conventional hadron calorimeter for jets. The current status of FOCAL R&D project will be presented.
