Outline TRD tasks in project planner l Geometry l Other topics l l Reconstruction Alexandru l HLT Status
Project Planner: TRD directory: FDR directory:
TRD – Calibration/Online – DCS l Pretrigger and configuration file (Christoph, Frederick) 30/06/08 ¡ Preprocessor implementation done – Reads file from FXS – XML parser in pre processor for data to OCDB ¡ In SVN and runs success fully in preprocessor tests conversion
TRD – Calibration/Online – DCS l Check DCS data points 30/09/08 ¡ DCS side: – File format defined: XML – Communication to DCS boards: Instructions via channel, return XML file via ACK channel – Test setup existing ¡ To be defined still: – Final datapoints for configuration and pretrigger files ¡ Also: check of already existing data points – Seems to be ok now. . . CMD
TRD – Calibration/Online – DAQ l Two DAs on DAQ ¡ ¡ ¡ l Pedestals algorithm (run type: PEDESTAL) Drift velocity (run types: PHYSICS or STANDALONE) Details: see Raphaelles presentation last offline week After some iterations the DAQ DAs are now finally operational as intended at P 2 (Raphaelle) ¡ Tested with real cosmics data
Preprocessor status (16/6/08)
TRD – Raw Data Format l Raw data format check and handling of data corruption (Min. Jung, Christoph) 31/07/08 ¡ ¡ l Adapt the raw data reading to eventual changes in the format. Handling and monitoring of raw data corruption Final (? ) update of Ali. TRDraw. Stream. TB last week Update of raw data simulation (Min. Jung) 30/09/08 ¡ ¡ ¡ Ali. TRDraw. Stream. V 2 (sim. ) and Ali. TRDraw. Stream. TB (test beam and cosmics run) Adapt raw data simulation to latest changes only one version New manpower assigned (Woo. Jin)
TRD – Quality Assurance l Reference distributions for QA (Sylwester) 29/08/08 ¡ ¡ ¡ Define and introduce reference histograms for the QA procedures Implementation started (Ali. TRDqa. Build. Reference) Exemplary versions of histograms Definition of full set of reference histograms ongoing Should have some quick progress now
TRD – Reconstruction l Planning of Ali. Reco. Param (Alexandru) 31/07/08 ¡ ¡ ¡ Ali. TRDreco. Param according to official scheme Implementation existing, incl. OCDB interface Final changes currently being discussed with Cvetan und being introduced by Alex.
TRD – Simulation l Consistent treatment of ZS in digitizer (Ken, Christoph) 30/09/08 ¡ ¡ Currently ZS is applied during conversion digits raw data Had to apply additional threshold for digits file size slight inconsistency with ZS scheme 1 st step: Modification of digits container (diff. treatment of “real” zeros and “masked” zeroes. Currently being tested. New manpower (Hermes)
Geometry l Additional mother volumes for services (Christoph) 31/05/08 ¡ ¡ l Possible further iteration ¡ ¡ l Add additional mother volumes in the space frame to accomodate the services that do not fit into the existing TRD mother volume. Adds additional ~9 kg (Aliroot: 1586(+9)kg Reality: ~1650 kg) Once more detailed information from integration groups are available Screws, cables, etc. Backframe: TRD Services Overlaps in TRD geometry removed ¡ Thanks to Andreas!
Reconstruction l Mis match between pad numbering scheme in raw data and reconstruction ¡ ¡ ¡ Troubles in matching cosmics tracks from TPC Ordering needs to be swapped in Ali. TRDpad. Plane Not visible in simulated data Currently under test, has to be checked for side effects, etc. Should be fixed these days
Tracklets from L 1 Trigger l Simulation of TRD L 1 trigger ¡ ¡ ¡ l TRAP chip tracklet finder (Clemens) Fast tracking in Global Tracking Unit (Jochen) Evaluation of trigger efficiencies Writing of tracklet data (Min. Jung, Jochen, Alexandru) ¡ ¡ Definition of common base class Ali. TRDtracklet. Base To be used for tracklets from raw data, simulation and reconstruction 1 st versions existing TRD. tracklets. root (not in default reconstruction)
Other Topics l Memory leaks ¡ ¡ l Fixed in simulation Reconstruction under investigation (some already removed) Simulation of Ar/CO 2 ¡ ¡ Ali. TRDSim. Param: : Set. Argon() Time response implemented Tail cancelation parameter in Ali. TRDfee. Param Material in geometry adapted parameters in Step. Manager. Fixed() (ionization potential, etc. )
Conclusions l Currently 6 open tasks ¡ ¡ 2 can be closed soon 2 with new manpower l Hope to close raw data chapter soon l Final touches on DAs and FXS l Immedeate reconstruction of cosmics data ¡ ¡ Very important information Still some bugs turn up pad mapping
HLT TRD Status Konstantin Antipin Henner Buesching and Kurt M. Barry
HLT: : TRD Main components are in place l Offline code is used l Mainly monitoring so far l Tested on cosmic data l General scheme: Raw Data In HLT Clusterizer Publish Selected Events Track Finder Physics Trigger GUI
HLT: : TRD Status Currently running: HLT: : TRD current chain RORC Clusterizer Monitoring Tracker Calibration File. Writer 1 is used 2 monitoring scheme is changing 3 not implemented
HLT: : TRD To. Do l Speeding up the code: ¡ l New monitoring scheme ¡ ¡ ¡ l A lot of room for improvement TRD Worker <=> GUI concept used for TRD monitoring Need in HLT for standard monitoring tool for all detectors Generalize TRD concept to be adoptable by other detectors Merge TRD+TPC track ¡ Need in algorithm to quickly match and prolongate tracks
FDR – 2 nd Phase – TRD l List of DCS for Shuttle ¡ l See TRD task “Check DCS data points” (30/09/08) FXS file list ¡ ? ? ?
FEE Simulation + Trigger l New simulation of online tracklets (Clemens Haltebourg) ¡ ¡ l Implementation of real algorithm (TRAP chip) (Ali. TRDmcm. Sim, Ali. TRDtrap. Alu) To be added to raw data (as in real raw data) Needed for L 1 trigger studies Next: online PID hardware stream efficiency Simulation of online global tracking unit (GTU) (Jochen Klein) ¡ ¡ Algorithm as implemented in FPGAs Code available, needs to be interfaced to tracklet simulation
