X.Dong, USTC/LBNL Feb. 20th, 04, STAR Collaboration Meeting 1 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

Feb. 20th, 04, STAR Collaboration Meeting X.Dong, USTC/LBNL 2 TOF detectors in Run IV TPC pVPD east pVPD west Au TOFx East-TPC TOFpTOFr x y Au 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 ( channels totally)

Feb. 20th, 04, STAR Collaboration Meeting X.Dong, USTC/LBNL 3 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 ( 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

Feb. 20th, 04, STAR Collaboration Meeting X.Dong, USTC/LBNL 10 Ongoing Makers IV TOF in MuDst: ---- MuTof introduced in MuDst TOF Hit TOF Cell MuTofFill Maker – write MuTof 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 pVPD Fill Maker ?

Feb. 20th, 04, STAR Collaboration Meeting X.Dong, USTC/LBNL 11 Summary  Online DAQ corresponding change for additional TOFr channels, little changes for other online software  Many new introduced structures in dbase --- calibration structure on the way --- request corresponding changes for the Makers or Utilities  Geometry changes in GEANT due to the position change of detectors this year  Most of the offline Makers are ready to be committed for the coming production

Feb. 20th, 04, STAR Collaboration Meeting X.Dong, USTC/LBNL 12 Outlook Preliminary timing resolution ~120ps Preliminary calibrations for Run IV Great thanks to the Software Group & … helpers! With the development of software, important physics will come out soon! Overall slewing correction
