TOF Software Progress Xin Dong, for TOF Group • TOF detectors in Run IV • Online software • Offline software -- Data base & Geometry -- Makers - match - calibration - simulation and embedding - MuDst • Summary & Outlook
TOF detectors in Run IV y • Some changes this year: • pVPDs moved ~4” further from Z=0 • TOFp moved one slot clockwise when facing west from the east side --- read out channels no change (41) • TOFr did not move, but the tray size and module positions in the tray changed --- First 20 modules (out of 32) in the tray have read-out electronics ( 72+48 channels totally) x East-TPC TOFp TOFr TPC pVPD east pVPD west TOFx Au Au
Online Software ‣Online software extended to 3 CAMAC crates in order to accommodate the read-out of 48 additional TOFr channels. ‣ new TOF raw data format (41+72+48 channels) required similar changes to the offline DAQ reader. ‣ Clearly we still have issues with the TCD-Bira communications which show up in TOF DAQ. --- mostly due to a hardware problem, not a software problem • -- TOFr HV is now only one channel. Software was updated • accordingly and so was its interface with SlowControls. • -- TOFp HV. No changes, only updated the Cell Mapping for • its SlowControl interface • - TOFr Gas. No changes. • - SlowControls interfaces. Reviewed the Red/Yellow alarm • settings and made them available as a document
TOF Offline Software Framework STAR/TOF DAQ GSTAR geant hits TOF DAQ Reader, TOFMaker TOF Mixer Maker TOF Simulation Maker TOF Data TOF Match Maker StEvent TOF MCCell/MCSlat TOF Cell/Slat TOF Collection TOF Calibration Maker TOF Hit TOF MuFill Maker + MuDst Maker MuDst TOF
TOF geometry & dbase TOF Geometry • Find the tracked cell/slat from a Helix • Coordinates transferring • Initialization from GEANT GEANT definition change due to the geometry & position change this year Data Base Many new introduced structures • TOF configurations --- ready --- pVPD configuration --- pVPD Strobe events configuration --- tof detectors configuration --- tof Tray configuration --- tof Module configuration • DAQ mapping --- ready --- tof DAQ mapping • Calibration parameters --- ongoing --- tof T0 (timing offset) --- tof Correction (overall) --- tof Correction (each channel) • Simulation parameters --- ready --- MRPC simulation parameters • TOFp Geometry --- need to be updated this year
TOF Collection in StEvent TOF Data: Raw ADC, TDC in each DAQ channel 42 + 6 + 72 (120) TOF Cell/Slat: Cells/Slats with track matched Cell/Slat Id, ADC, TDC, associated tracks, projected position MCCell/MCSlat: Additional MC information TOF Hit: After calibration Physical tof, β, pathlength, etc.
Ongoing Makers I TOF Match Maker: Fired channels from DAQ Matched within one pad distance Projected cells from global tracks Get rid of multi-hit cells Order cells for cross talks Save those have primary tracks into TOF Cell Collection TOFp Match Maker already in library, TOFr Match Maker ready to be committed
TOF Data in StEvent Calibration parameters from dbase pVPD calibration – start time TOF Cell in StEvent Time-of-flight correction Write TOF Hit in StEvent Ongoing Makers II TOF Calibration Maker: Fast offline data for calibration Waiting for dbase structure ready to do corresponding change for checking in
Ongoing Makers III TOF Simulation Maker: Simulation parameters in dbase Geant hits Cell response simulation Ready to be committed in Write raw ADC & TDC in TOF Data TOF embedding Makers: TPC embedding TOF Data from DAQ TOF Data from simulation Tof Mixer Maker ? Need corresponding change for dbase configuration read-in Tof association Maker
Ongoing Makers IV TOF in MuDst: ---- MuTof introduced in MuDst TOF Hit MuTofFill Maker – write MuTof TOF Cell ? pVPD Fill Maker Corresponding changed MuDSTMaker Write into MuDst Ready to be reviewed and committed Makers summary: • Almost all are ready! • Need to be committed ASAP before production
Online DAQ corresponding change for additional TOFr channels, little changes for other online software • Geometry changes in GEANT due to the position change of detectors this year • Many new introduced structures in dbase --- calibration structure on the way --- request corresponding changes for the Makers or Utilities • Most of the offline Makers are ready to be committed for the coming production Summary
Outlook Preliminary calibrations for Run IV Overall slewing correction Preliminary timing resolution ~120ps With the development of software, important physics will come out soon! Great thanks to the Software Group & … helpers!
