BABAR Background Remediation Home Page

Background remediation means to live happily with the " Background Monster" .

Some people have manifestly already succeeded !

Background remediation Home pages for Systems:


  • Creation of the Background Remediation Group :19/11/98
  • Goals: Determine the maximum permanent background level that allows BABAR to operate and performs physics. Make sure that BABAR can provide enough information to monitor the background and protect its subsystems.
  • The people
    • Steering committee : Pat Burchat, Andy Lankford, Terry Geld, Tom Himel, Bob Jacobsen, Iannis Karyotakis, Witold Kozanecki, Adrian McKemey, Tom Mattison, Gregory Dubois-Felsmann
    • First meeting : Dec 10. Minutes
    • Meeting January 6, 8.30 am. Minutes
    • Meeting January 19, 2 pm Minutes
    • Meeting March 30, 10 am Minutes
    • Detector contacts :
    • ‘Hardware-oriented’ C. Hast, P. Burchat (SVT) , A. Roodman (DCH) , A. McKemey (EMC), B. Wilson (DRC), H. Band (IFR), T. Liu (Trigger)
    • ‘Offline-oriented‘ N. Kuznetsova, M. Witherell (SVT), R. Stroili (DCH), G. Hamel de Monchenault (DRC), H. Marsiske (EMC), R. Baldini (IFR), F. Kral , L. Galdney(Trigger)
  • The meetings and information channels
    • The Background Remediation Hypernews Forum
    • During the run, some mcc information day by day
    • Background remediation weekly meetings will take place by video/phone on Fridays at 9.30 am (Pacific time). At SLAC, the venue will be the Pom/Flora video conference room. To Join by phone, call (1)973 321-2000, pass code 14198#
    • The video sites are presently : SLAC-2, LBNL, UCSD, CSU, LAL Orsay, Saclay

Special Topics

The January workshop (13-15 January 1999)
  • The talks are available as hyperlinks in the detailed schedule

  • List of Open issues for the workshop
  • Global schedule
  • Detailed schedule
  • Executive summary
  • BABAR as a background detector
    • With exception of the PIN diodes system, all other present background dedicated detectors will be replaced by BABAR. Each BABAR subdetector will have to provide a background monitor signal and a protection signal, to prevent radiation damage. The requirements for these two types of signals are to be found here.
