  2. DCS infos for RPC DQ • The RPC Power System, the Trigger and RO electronics, tightly but not trivially interconnected each other. • The interconnection rules used to determine the DQ and the status of the relevant detector elements. • DQ granularity is the Trigger Tower ~ 400 flags { 32 Trigger Sectors (Φ) x 7/6/5 Towers (η) x 2 Sides A/C (z) } • DQMF algorithm will run to determine the partition DQ final flags for DCS side ρ High PT Station Y HV tower RO tower ΔΦ Low PT Station η X Muon DCS DQ Flagging

By using these info we can calculate: “Tower Status” ( Integer) and “Tower Quality” ( Float ) T.T. DQFlag calculation Red if…T.Status < x Green if … T.Status > x Muon DCS DQ Flagging

  4. to COOL Trigger Tower DP structure • Control Manager running in a separate PVSS system: ATLRPCMON • Control Manager running to update the values at any “relevant” change • DQ variables calculated via dpFunction and dpConnect to the channels Muon DCS DQ Flagging

  5. Status quo • Created the DPs “Station”; starting point to create all the info needed by DQ (Alessandro). • Created the DPs “Trigger Tower” with all the info to be stored in COOL Database. • The elements included into the DPs “Station” are updated at any change of the LV (Vee,Vpd,Vpad ) or HV system (HV Channels). This is done independently from FSM masking. • The elements included into the DPs “Trigger Tower” (“..Status”,“..Quality”,”..Majority”) are calculated as soon as the corresponding Station DPe change. • At the present moment we do not take into account the Trigger Tower overlap (“first order” approximation) Muon DCS DQ Flagging

  6. To do list… • Create the COOL table by tomorrow (MeSlava K.). • Activate the PVSStoCOOL process by tomorrow (MeSlava K.). • Activate the DCS status calculator by end of this week (Me & Giulio A.Katharine L.). • Get some basic info from DDC (e.g. # RUN, Lumi block ) by april? (Alessandro P.  Enrico P.). • Create an U. I. for the shifter to look the present status of the detector from the different points of view: Stations, Towers… by april. (Me) • Try to define better the Dpe “Quality” for Trigger Tower (Vth, Igap..) by may. • Try to use further info from DDC (Trigger Tower rates, Vpad initialized..) by may. • exchange of feedbacks DAQ DCS. t Muon DCS DQ Flagging

  7. Conclusions and outlook • Status of RPC DCS DQFlags production advanced. • Useful overview of trigger tower status for DQ and DAQ. • Opportunity to improve the quality of the info stored in COOL taking into account further detector parameters. • Need for define the edges of these tools. • Need for proper documentation.

  9. Phi strip panel …. High PT PAD box ready Athena RO panel PHI Athena RO panel ETA …. RPC detector Gas gap Eta strip panel RO panels into DCS • RO panel used by Athena reconstruction represent the maximum • granularity reachable by the DCS •  ~ 8000 RO panels (including corresponding gas gap). • The COOL table could be made of two columns : • 1. ATHENA compatible id. • 2. A numeric describer which integrate a Boolean evaluator (1/0) • and an analogical quality (how much GOOD is the panel..). • To be implemented. Some overlap with Tower and Station objects. Muon DCS DQ Flagging
