Research Activities:


From 2000 I carry out my research activities playing a leading role in the Bologna ALICE-TOF group, that was responsible for the construction of the Time Of Flight System (TOF) of the ALICE experiment at the CERN LHC (Large Hadron Collider).

       The aim of ALICE is the study of the heavy ion (Pb-Pb) collisions at a centre-of-mass energy of 5.5TeV/nucleon-pair, i.e. the study of the hadronic matter in extreme energy density conditions. In this scenario a new state of matter, the Quark Gluon Plasma (QGP), with unconfined quarks and gluons should be created.

In this experiment the Bologna group has the responsibility for the construction of a large detector (~160m2 total area) devoted to the charged hadron (π, K, p) identification in the momentum range 0.5-2.5 GeV/c for  π/K and up to 4 GeV/c for K/p, using the particle Time Of  Flight measurement.

For a 3 sigma separation between charged hadrons in this momentum range a global time resolution smaller than 100 ps is needed.

In order to satisfy this requirement the Bologna group has developed the Multigap Resistive Plate Chamber (MRPC) that allows to obtain an intrinsic time resolution smaller than 50 ps and an efficiency near to 100%. Moreover this chamber can operate at high rate (up to 1kHz/cm2) with the same performances.

The TOF detector covers a cylindrical surface with an inner radius of 3.7 m in the polar angle acceptance  

 |θ-90o|<45 o, over the full azimuthal angle; the basic element of the detector is a MRPC of 120x7.4 cm2 (active area) divided into 96 readout pads.

The full system with 1638 MRPCs and about 157000 pads, is divided into 18 azimuthal sectors along the beam directions. In each sector there is a mechanical structure, called SuperModule, that containing 5 modules 

(one central with 15 MRPCs, two intermediates and two externals, each with 19 MRPCs ).



1) Research Activity during the Degree Thesis:


                During the thesis work I spent one year at CERN (“Centre Européen pour la Recherche Nucléaire”).

       I built several MRPC prototypes with different characteristics for studying their performances.

       I played an active role during many beam tests of the prototypes at the “East Hall” (T10 experimental area) of the CERN PS (“Proton Synchrotron”) and I analyzed the collected data. This study has allows to determine the MRPC final geometry and to optimize the construction specifications.



2) Research Activity during the PhD:


In April 2002 I started the PhD course at the Alma Mater Studiorum, University of Bologna.

During the following three years:


  • I developed the MRPC assembly and construction procedures in order to simplify and speed up the production of 1638 chambers needed for the ALICE TOF.
  • I worked on the treatment with a resistive paint and on the selection of 6552 glasses used as MRPC external electrodes where the high voltage is applied.
  • I played an active role in the MRPC mass production.
  • I took part in several beam tests at the CERN PS and in cosmic ray tests at the Bologna TOF group laboratory.  
  • I studied the MRPC performances in terms of efficiency and time resolution as a function of construction and operation parameters, with a special care of the response uniformity along each single MRPC and among different MRPCs.
  • I tested the MRPC performances as a function of the different electronic-board prototypes (“front-end” and “readout” electronics) for the choice of the final configuration.
  • I developed the assembly procedure for the TOF modules.
  • I worked on the construction of the first TOF module and on its beam-test performance study. 


3) Research Activity as “Post-Doc”:

As a Post-Doc

  • I worked on the MRPC mass production.
  • I worked on the TOF modules assembly.
  • I developed the assembly procedure for the TOF SuperModules.
  • I coordinated the TOF SuperModule assembly.
  • I took part in all SuperModule installations inside the ALICE Space-Frame and their commissioning.
  • I took part in the ALICE global commissioning and cosmic runs for the TOF detector and partially for the ALICE DAQ.

4) Research Activity as University Researcher:

  • Since 2009 I took part in the continuous ALICE data taking, first with proton beams at 0.9, 2.36 and 7 TeV, then with lead ion beams at 2.76 TeV per nucleon pair and with proton/ lead beams (in the configuration p-Pb and Pb-p) at 5.02 TeV per nucleon pair. Moreover in these years I was ingaged in the maintenance of the TOF detector during the technical stops of the accelerator. 

During these years I made several talks on my research results during TOF group meetings, ALICE Technical Board meeting and in international schools and conferences.




  • Since 2005 I have been responsible of the TOF MRPC construction.
  • Since May 2006 I have been responsible of the assembly, installation and commissioning of the TOF SuperModules at CERN.
  • Since 2007 I'm responsible of the ALICE TOF gas system.
  • Since 2007 I'm responsible of the ALICE TOF cooling system.
  • From 2007 to 2011 I was the "System Run Coordinator" of  TOF group in ALICE. I was the contact person for the TOF group in the ALICE meetings for the weekly planning and the daily check of the work progress in the subdetector installation, commissioning and data taking. 
  • In September 2010 I was endorsed by the ALICE Run Coordinator as Period Run Coordinator for the experiment.
  • During the proton and lead ion data taking I was many times the Shift Leader in the framework of the ALICE collaboration and on September 2010 I was the Period Run Coordinator for the experiment. 
  • Fron January 2012 to February 2013 I was endorsed by the ALICE Collaboration Board as Run Coordinator of the experiment.
  • From March 2013 I'm the co-Coordinator of the ALICE "Consolidation Task Force" whose task is to optimize the data taking procedures and the performance of the detectors, Data Acquisition and Trigger taking into account the  luminosity increase during the LHC - RUN2 period.
  • From June 2013 I'm the ALICE TOF Technical Coordinator.
  • From 22 September 2016 I'm the Bologna Coordinator of the experimental activities in Nuclear Physics (both low and high energy) of INFN (G3) and member of the National Scientific Committee of G3.
