Activity report from CAF group Marcello, Davide, Pigi,Camilo, Salvatore, Orso, David, Silvia,Georgi, Anna, Haiyun
CAF strategy • What kind of data do we have ? • Minimum Bias (low PTmuon mostly from secondary vertex) • Beam Halo (horizontal muon tracks) • Cosmic • What we can study with those events ? • Noise and occupancy • Endcap efficiency • EVENT SELECTION • STUDIES
Whatwe are doingnow ? • Beam Halo selection • Trigger based (Salvatore) ready • CSC segment based (Haiyun) almost ready • Minimum Bias selection • RPC rechits + tracker tracks (Orso) • Detector Studies • RecHits distributions with MB and Cosmic (Orso) • CSC/RPC correlation (Camillo, Haiyun, Georgi) • Efficiency with beam halo events (Camillo) • Trigger Studies: CSC versus RPC (Maciek) • Noise (Silvia, David and shifter) • BX distribution (Anna and Pigi)
Noise History from DQM (David Lomidze) "noisy strip" state: strip occupancy 3.5 times greater than average occupancy (from roll occupancy histogram) "noisy chamber”: average multiplicity > 6
