  1. D0 Saclay activities 99 • People • Computers • Activities • hardware • software Workshop D0 Praha

  2. Activities D0 Saclay 99 • People • Physicists :11 tenures • 8 with involvement • in Atlas (5) • CMS(1), • Aleph(1), • H1 (1) • 3 on trigger hardware/software • Computer engineers • 1 part time (software installation) • 1 full time on level 3 • 1 student starting now Workshop D0 Praha

  3. Activities on trigger • Same people working on the Atlas trigger • Hardware: FIC • design and construction of 12 units used in the level2 standard crate • Installed and test in June at FNAL • Trigger model (cf. Atlas): starting very soon • Level 3 • 1 computer engineer full time • MC data  « ADC » : in charge of package RawDataBuilder: packing MC chunks to look like raw data chunks Workshop D0 Praha

  4. Computing in Saclay • Saclay has some envolvement in the Lyon computing center • In Saclay: • 1 DEC UNIX with KAI problem to get D0 code installed because no « official »releases on 1 PC sous LINUX avec KAI • 1 PC under Linux • Code Releases regularly installed • Link with FNAL • link RENATER to ATM 155Mb, 100 mb shared by Saclay and other users • Being negociated: ~1 Mb dedicated between Saclay and FNAL Workshop D0 Praha

  5. Software Activities • Main involvement: testing D0STAR/Simpp • Pre-Simpp era: testing D0gstar output (In Fortran) • some bugs found in GEANT 3.21 • Some problems found in geometry definition for some detectors • After Simpp: • code in C++ to build hbook histos for (almost) available information (generated tracks, hits, digi, reco,..) • Code for writting « general » Ntuple with variables above • maintenance and developpements • Tools for studying tracking from MC_exam et Ntuple • Magnetique field Workshop D0 Praha

  6. Physics • Contacts with theorists in Saclay • See talk by Christophe • for Susy with R parity violation, • Diffractive phenomena: analyzis of RunI data using algorithms used to fit H1 data du run I • Interest in physics ‘ with ’ the b quark • Interest in: • tracking • electron ID • muon ID Workshop D0 Praha
