Le nucléaire au service du développement High Energy Physics History Active community in high energy physics theory, Mathematical Physics and cosmology Tight collaborations with ICTP – Trieste- and some IN2P3 laboratories No official participation of Morocco in experimental high energy physics programs In the middle of 1990’s formal collaboration with IN2P3 and CERN In 1996 first Collaboration agreement of CERN with an Arabe and African country First participation of Morocco in the construction of a major international scientific instrument First structuration of research in Moroccan Universities especially by the creation of National Thematic Networks like National High Energy Physics Network (1996) Construction of the presampler of the ATLAS Electromagnetic Calorimeter with LPSC – Grenoble – FRANCE & KTH – Stokholm - SWEDEN 5

Reseau Universitaire de Physique des Hautes Energies (RUPHE) Moroccan High Energy Physics Cluster Founded in 1996 : – University of Casablanca – University of Rabat – University of Oujda – University of Marrakech – University Of Tanger – CNESTEN – Rabat WEB site – WEB site Funding Agency : Centre National de La Recherche Scientifique et technique (CNRST) 6 20 Professors 20 Students

Le nucléaire au service du développement Collaboration Phases 1996 Signature of ATLAS M&O An International Scientific Collaboration Program (PICS) 1997 to RUPHE and LPSC Grenoble (CNRST-IN2P3) Integrated Action from 2000 to 2003 International Research Group (GDRI) set up by CNRS 2003 to signature of the CALICE M&O for the ILC program 2008 creation of the International Associate Laboratory (LIA) International Laboratory for Collider Physics (ILCP) 7

Morocco In ATLAS since 1992 From 1992 to 1998, we study : - electronics radiation hardness - Pollution of liquid Argon - Material selection for LAR Electromagnetic Calorimeter Construction of neutron irradiation station in 1992 Since 1996 Morocco is officially in ATLAS - After an unanimous vote by the ATLAS collaboration Board

Construction (LPSC-Grenoble and KTH-Stokholm) of the ATLAS electromagnetic calorimeter presampler from 1998 to 2003 – Preparation and test of more than Anodes High Voltage long duration test : - With 9 plates 450 anodes at 3 KV between the outer and the inner layers for 2 days -Rejection rate less.1% (E.A Anodes)

Electrical test bench : -LCR meter -High voltage supply -rail and 2 arms - PC with LabView 2 Cleaning room at Casablanca and Rabat: 8 persons -Thickness measurement : friction clutch micrometer -Resistance soldering : 4 x 1M  by Anode -Visual control : Binocular -H.V long duration test (24 hours) : 4 plates (200 Anodes) -Electrical test : test bench -Labelling, Packaging and shipping to MOC factory (France)

Presampler of the ATLAS E.M. Calorimeter Grenoble (LPSC) – Stokholm and Morocco 1 wheel of 32 sectors Since 1996 our participation focus on : - Construction of the presampler - Prototype Beam test (shifts, …) - Beam test data analysis - Installation and commissioning in the ATLAS pit - Electronic calibration - Cosmic Data analysis - First LHC Data analysis

Present status and progress Up to now about 15 Thesis had been defended in ATLAS Framework and more than 50 International publications About 10 PH.D students are working now on ATLAS experiment and CALICE – ILC Since 2010 : One Fellowship had been set up by the HASSAN II Academy for student working at CERN (2010 Laureate : M. Gouighri) – Selection of the candidate by an International committee from IN2P3, CERN, ATLAS experiment, the Academy and CNRST representatives and the foundation “Sharing Knowledge”. Computing centre connected to LCG Grid at Casablanca with all the ATLAS software and will be soon configured as a tiers-3 New project with LPSC and CPPM : Installation of a cosmic neutrino telescope in Taza-Morocco, Grenoble-France, Marseille-France 13

Present status and progress LIA : Laboratoire International Associé since 2010 with : 6 IN2P3 Laboratories (13.7 FTE), 2 Swedish laboratories (8.6 FTE) and RUPHE (18.5 FTE) From September 2010 we organize at Casablanca the annual CALICE meeting In the spring of 2011 we organize the school EPAM-2011 On High Energy Physics at TAZA-Morocco in collaboration with SFP. education : International Master In : High Energy Physics and scientific Computing since 2005 with the participation of Teachers members of GDRI or LIA. 14
