This paper will present the first results from irradiation tests performed on the ALICE TPC Readout Control Unit 2 (RCU2). The RCU2 is developed in order to double the readout speed with respect to the present RCU1, which then will fulfil the requirements for LHC RUN2. While the present RCU1 is based on an SRAM based FPGA, whose configuration memory has shown to be sensitive to single event upsets, the newly released Flash-based Smartfusion2 FPGA from Microsemi has been chosen for the RCU2.

“…The PCM method measures photons and meson yields by reconstructing e + e − pairs proceeding from photon conversions in the material of ALICE inner detectors. PCM measurements use the ALICE Inner Tracking System (ITS [4]) and the Time Projection Chamber (TPC [5]), measurements using this method have full azimuthal acceptance and 1.8 units of pseudo rapidity coverage. 3. π 0 invariant yields in pp collisions at √ s = 0.9, 2.76, 7 and 8 TeV The ALICE experiment to this date has measured the invariant yields of π 0 at four √ s. The measurements indicate a power law dependence at high p T with a measured power value of n = 6.0 ± 0.1 at √ s = 2.76 TeV, a value lower than what has been observed with measurements performed at lower √ s energies [6].…”

One of the key signatures of the Quark-Gluon Plasma (QGP) is the modification of hadron transverse momentum differential cross-sections in heavy-ion collisions (HIC) as compared to proton-proton (pp) collisions. Suppression of hadron production at high transverse momenta (pT) in HIC has been explained by the energy loss of the partons produced in the hard scattering processes which traverse the deconfined quantum chromodynamic (QCD) matter. The dependence of the observed suppression on the pT of the measured hadron towards higher pT is an important input for the theoretical understanding of jet quenching effects in the QGP and the nature of the energy loss, while suppression towards lower pT gives information about collective behaviour. The ALICE experiment at the Large Hadron Collider (LHC) performs a variety of measurements including the spectra of neutral mesons and kaons at mid-rapidity in a wide pT range in pp, p-Pb and Pb-Pb collisions. An overview of ALICE results in HIC and pp collisions at √ sNN =2.76 TeV of neutral pions, kaons and eta mesons as a function of transverse momentum (pT) and centrality will be presented. Ratios η/π 0 , K ± /π ± as well as comparisons to model calculations will also be discussed.

This paper presents the solution for optimization of the ALICE TPC readout for running at full energy in the Run2 period after 2014. For the data taking with heavy ion beams an event readout rate of 400 Hz with a low dead time is envisaged for the ALICE central barrel detectors during these three years. A new component, the Readout Control Unit 2 (RCU2), is being designed to increase the present readout rate by a factor of up to 2.6. The immunity to radiation induced errors will also be significantly improved by the new design.
