• 12:30~ N-C Meeting

TGC Online SW

Configuration SW

• download the software from SVN (not CVS) --> 1st attempt
  • SVNROOT=svn+ssh://svn.cern.ch/reps/muondaq
  • unset CVSROOT
  • svn co $SVNROOT/package_name/trunk package_name
  • svn repository
• update them with the latest files (Okumura's correction and TgcTtcvi correction)
  • recompile in local environment --> OK
  • upload to SVN --> not yet (done on 2nd June)
  • recompile in standalone/global environment --> not yet
• fixed bug on TgcTtcvi command used for PsReset
  • To send PsReset (0x80) from TTCvi as asynchronous command (8bits),
    a command to return the signal to LOW (0x0) is required to send after sending user defined command(*).
  • In the MaulalTtc command, this procedure was implemented. But I missed it...
    As the result, PsReset signal was kept as HIGH, and the VME API could not take any JRC route to configure PP/SLB ASICs.
  • Width of the pulse is adjusted to more than 10usec using usleep(). (same way implemented in ManualTtc)

• (*) User defined command
  • 7th and 8th bits of asynchronous short command are assigned for user command.
    In case of TGC,
    • 0x80 is for PsReset
    • 0x40 is for TestPulseTrigger
    • 0x20 is for DcsReset.

Configuration Database

• Nothing to be done.

Physics

• Daily discussion: Measurement of W-boson polarization from top quark decay in ATLAS (by Hasegawa)
• My interests
  • What is the polarization vector?
  • What is the renormalization?
• Today's HEP arxiv
  • Unparticle Effects on Top Quark Pair Production at Photon Collider
    (hep-ph, arXiv:0802.0236)
  • Angular correlations in t-channel single top production at the LHC
    (hep-ph, arXiv:0905.4754)
