5 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 5 The CMS Trigger and DAQ 1)Read Out Units (Rus) Constructed and tested in collaboration with Greek Industry, 22 RU units (IOPs) Validated the feasibility of the Trigger and DAQ System IOP card with on board CPU, 3 PCI buses Altera FPGA 2) Global Trigger Processor Emulator – GTPe: 10 Full systems delivered to CMS. Designed, Built, mounted and tested at INP. FPGA 400kGates (Mixed firmware VHDL and Handel-C) developed at INP Capabilities: Random Triggers up to 4 MHz (nominal 100kHz), Event Packaging, Communication to Event Manager, Accept backpressure signals from detectors and DAQ partitions CMS Trigger and Data Acquisition System: LHC collisions at 40MHz, Level1 Trigger at 100kHz High Level Trigger at 100 Hz

10 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 10 INP Computer Cluster – CMS GRID INP Cluster currently has ~ 100 CPUs ~ 25 Tbytes storage space Has been a Tier-3 site in the CMS Grid infrastructure until last year. Since the beginning of 2010, it operates as a local cluster, with all the CMS software fully operational – and serves the local users of the Institute.

11 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 11 LHC Principal Goal : Explore a new energy/distance scale Extra Dimensions SUSY partners Dark matter Tiny Black Holes q-g plasma SM(t,b, QCD,E/W) … !!! UNEXPECTED!!! My life as a boson

12 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 12 CMS Demokritos Physics - I Test-Beam & Physics Tools development: ECAL test-beam data analysis. Development of π0 rejection algorithms for converted and unconverted photons. ECAL Dead Channel recovery algorithms. Physics Analyses at simulation level FCNC decays of Top quarks, SUSY search at LM4, MSSM Higgs searches, Little Higgs searches. Physics Analyses on first CMS/LHC data : Cross section measurement of W and Z in the electron channel (results shown in ICHEP) Measurement of Zγ (ISR) production and TGC measurement

13 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 13 CMS Demokritos Physics - II

14 G. Daskalakis INP activities at CMS/CERN NuPECC Meeting – Athens 8.10.10 14 Summary - Outlook The CMS Group of Demokritos has made marked contributions to the construction of CMS in the areas of the Pre-shower detector & Trigger/DAQ as well as in the preparation of the software & Physics. Effort is currently shifting to physics exploitation of the CMS detector by analysing the first 3 pb -1 of data already delivered by the LHC. Most probably we ll have 30 pb -1 by the end of 2010.
