Vito Palladino Straw Working Group 23/3/2015 Plans for the 2015 Run Vito Palladino Straw Working Group 23/3/2015
Hardware Gas leak to repair in Station 4 HV discharge in Station 4 to be understood SBC Move to local accounts (AFS is not stable enough) COVER Make safer the masking of the channels Check the multi-hit and FIFO full flags SRB Fix the NIM outputs (patch to be applied on all boards) Heat sinks installation Trigger matching

Hardware II One DATA cable to be changed in Station 1 Installation of the shielding for the cable trays (Reminder: the data cables are RJ45 but the signals are LVDS) Gain monitor module Full development setup in 154 (16 covers,1 or 2 SRB(s) and a complete MPOD system) 16ch ISEG HV module repairing Temperature sensors to be installed on the manifolds

Run Control Init procedure: Recognize PLLs problems + automatic actions ( => restart ALL the PLLs ) Recognize links problems + automatic actions Add masking of not connected straws Add reset of internal links SOB/EOB Automatic checks + actions: Masks Connection to COVERs Thresholds PLLs Noise spikes (induced) Automatic reload of COVER parameters in case of reset Readout of the HW configuration

Raw Data Analysis Toy Montecarlo to estimate the data throughput in case of trigger matching, with various trigger rates. Exercise the trigger algorithm(s) Generate a root tree from the raw data (Straw only) Data merging Searching for problems in COVERs connectivity Multi-hit and FULL full flags Noise spikes
