1 The Summer Begins: CERN Kristin Beck

2 02.07.2008University of Michigan REU at CERN2 of 10 Introductions High Technology High School 2002-2003 Hometown: Colts Neck, New Jersey School: University of Rochester Academics –BS, Physics –BA, Mathematics –Minor: Music

3 02.07.2008University of Michigan REU at CERN3 of 10 Introductions Advisors: –Dan Holmes –Darin Acosta Office Mates: –Joe Gartner –Khristian Kotov –Dayong Wang

4 02.07.2008University of Michigan REU at CERN4 of 10 CMS LHC = Large Hadron Collider CMS = Compact Muon Solenoid “General purpose detector” Many specific subsystems

5 02.07.2008University of Michigan REU at CERN5 of 10 L1 Trigger uses LCT events from multiple chambers to reconstruct a particle’s path CSC Level 1 Trigger CSC = Cathode Strip Chamber CSCs consist of wires and strips arranged in a grid pattern Muons crossing through CSC produces an LCT (Local Charged Track)

6 02.07.2008University of Michigan REU at CERN6 of 10 CSC Level 1 Trigger 40MHz  100kHz  Hz CSC Level 1 Trigger selects up to 4 events per beam crossing (25ns) My role: verification and testing of CSCL1T through data analysis from cosmic runs (CRUZET2, CRUZET3)

7 02.07.2008University of Michigan REU at CERN7 of 10 Progress to date Developing facility with operating environment: ROOT, CMSSW (CMS SoftWare) Analysis sequence for displaying: –TF position data –LCTs in global coordinates –LCTs used to create tracks –Difference in η and φ for LCTs of a given track
