  • IU: Kei Moriya, Matt Shepherd
  • JLab: Eugene Chudakov, Hovanes Egiyan, Mark Ito (chair), David Lawrence, Paul Mattione, Dmitry Romanov, Simon Taylor, Carl Timmer, Beni Zihlmann

Announcements

  • Status of alpha release of CCDB. Dmitry worked on this during the calibration and conditions database (CCDB) during his last visit and is picking it up again. Right now he is working on the first alpha release.
    • The low-level API is done.
    • The make system is done.
    • JANA integration is not ready.
    • The user-level API is not ready
    • Goal for release: user-level API, but not Jana integration
Elliott commented that CLAS12 is interested. They would like to code to be kept in the 12-GeV repository. We will try to oblige. Dave will look into off-site collaborators checking out from the 12 GeV repository.
        2. Geant4 Tutorial: Mark
        3. danaevio and rawevent plugins, translation tables: Elliott 

heads up danaevio plug-in raw hit objects and reconstructed objects, generates evio tree that includes representation of those objects can be serialized, can be sent as a messge, can be printed paul will be testing this last feature

rawevent plug-in : data acquisition will write raw data from dana objects, list of crate slot channels, they make the structure and write to disk, need to take a hit, bar paddle and turn to crate slot channel would like to do it realistically question: is someone collaboration doing that serialization should be compatible with named pipes in new approach from Richard, this will be used translation tables

david: electromagnetic background , richard cannot reproduce, david can

 /group/halld/

lockf a pointer , ongoing problem , in mantis

  2. Review of minutes from the last meeting: all


  3. Non-reproducible results: Will

different results each time, seems to be in reconstruction code four vectors different from run to run number of particles different, charged particles and photons

beni has seen photons come and go

paul third time

david not the same events

reproduced beni's result, stale data hypothesis,

  4. Restructuring particle classes: Paul M.

Matt : displaced vertex: ks, ks itself could be member of a vertex

  5. Action Item Review: all
         * Recently Resolved
         * Outstanding Items 
  6. Review of recent repository activity: all 

eugene

turning part o tracker off for hardware problems • can be have a gsimko for gluex • do we have a tool to say that hits should be ignored? no is there any simulation of in-effiency

New Action Items

  1. Look into off-site collaborators checking out from the 12 GeV repository.

-> David

  1. Remind people to update their Mantis items. -> Mark
