  1. Activity report from CAF group Marcello, Davide, Pigi,Camilo, Salvatore, Orso, David, Silvia,Georgi, Anna, Haiyun

  2. 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

  3. 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)

  4. Beam Splashes

  5. 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

  6. Historical DQM is on the way

  7. CSC – RPC correlations (Camillo & Pigi)

  8. BX distribution - splashes Roll: RE+2_R3_CH02_C Roll: RE+2_R3_CH20_B Roll: RE+2_R3_CH20_C Roll: RE+2_R3_CH03_C Roll: RE+2_R3_CH21_C Roll: RE+2_R2_CH22_C Roll: RE+2_R2_CH29_B Roll: RE+2_R2_CH29_C Roll: RE+3_R2_CH20_A Roll: RE+3_R2_CH15_B Roll: RE+3_R2_CH16_B Roll: RE+3_R3_CH06_B Roll: RE+3_R3_CH06_C Roll: RE+3_R3_CH36_B Roll: RE+3_R3_CH36_C
