DT Sector Test Regional Mode Detector in UXC 55 DT station minicrate YB+1 S 10 MB 1, MB 2, MB 3 DT front end Barrel Trigger and readout data to Sector Collector and ROS on the tower Trigger Boards Read. Out Boards Server Board C C B Link LVDS copper link Towers in UXC 55 Counting room in USC 55 Opto RX in the PHTF backplane DTTF: makes trigger with coincidence 2 out of 3 (only looking at the trigger quality bit) Sector Collector ROS Opto link DT Track Finder Wedge. Sorter Barrel Sorter LTC in MTCC Sector Collector synchronizes trigger data from chambers and sends them to the PHTF (opto transmission 1. 6 GHz) D D U DTTF output to WS -> BS -> Lemo Trigger output (L 1 A) LTC -> TTCci -> TTCex Back to detector: SC crate and Minicrates

These Data in CMSSW Data recorded (with ROS 25) on DAQ PC dtfed 1, analyzed through the CMSSW chain. IGUANA event display is a powerful tool to check data quality (trigger configuration, chambers are functioning, hits are aligned) M. Zanetti

CSC Status • Fibers between detector and green barrack are re-cabled – final MTCC fibers – ~20 m shorter – CSCs have been timed in again. • First stable HCAL/CSC joint Global DAQ run performed this week. – CSC-Muon trigger over a different trigger path for HCAL • HCAL needed to retime their system. – stable running for several hours • Using CSC trigger, distributed via MTCC TTC hardware • Both subsystems provided data to Global DAQ (~1 M events) – however: HV trip of CSC which maximally overlaps with HE makes the data not very efficient. • High humidity likely to be the cause … unavoidable in SX 5 – plans: as soon as YE+1 is in its final position and HCAL has completed the final cabling another set of runs will be performed • Hopefully the first thing after next week …
