EUTelescope Developers Meeting

Monday 8 May 2017, 10:00 → 11:00 Europe/Zurich

• Installation
  • Take ROOT out of ILCinstall, have users install themselves -> Tom
  • EUTelescope installation issue
    • Fedora 24 works, C++11 flag causes problem, old gsl version, some environment variables aren't set correctly (esp. standard compiler)
    • We are also not using the most up-to-date version of ILCsoft
    • Post summary of our problems on ILCsoft issue tracker -> Tobias, Felix
    • Manpower needed!!! Tobias doesn't have time to help here
      • Tag new release with updated/working install scripts
      • Update to GBL version 2.0 -> will be using EIGEN instead of ROOT
      • Update ROOT version in reworked install script
    • New installer tagged in eutelescope github, see issue #348
      • Tobias' branch contains new installer version, see there
      • Problem with SLC6, manpower needed (or people need to figure that out themselves)
• Documentation
  • Tom's documentation for Pixel? -> report in Pixel TB meeting sometime
    • To be expanded for use by 'everyone'
      --> also announce in all interested testbeam users meetings
    • Pull request done for documentation
    • Virtual machines with working installation available
      • standard ones ready in a few days -> are online!
      • Tobias started docker image for VMs, should be faster than standard VM
        --> is this something we want to do?
        --> We get them for free due to CI -> switch to these at some point, but keep VMs for now
  • Updating/concentrating mailing lists for users and developers -> Edo, (Tobias)
    • One list for developers, one for announcements to users
      --> eutelescope-users, announce on github wiki page
    • Questions/discussions on issue tracker

• Clean up old code -> Tobias
  • Implement nice indentation using clang_format
    • Convention on Euler angles -> ALICE needs to change some processors, tbd next months
      --> will be documented on github-wiki

==> DONE!

• Tbd: remove some old processors
  • Starting to remove old style alignment -> backward compatible
• GBL code uses some old classes -> some old stuff not removed yet

• X0 measurement
  • Benni/Ulf's code, GBL-based (biased, because you put in a material estimate!)
  • Study resolution and impact of bias in GBL-method -> Hendrik
    • Cross-checking Hendriks processor with Benny Schwenkers code, results look to be consistent
  • Using Hendriks GBL branch Michaela reconstructed TB data -> Michaela will help implement in EUTelescope
  • Merge into GBL
     
• GBL
  • create more general version, compatible with current definitions -> Tom (Tobias)
  • Implement generalized track search (currently using triplet search for pattern recognition)
  • Implement track reconstruction in B-field
  • GBL code from Hendrik
    • Merged back into master branch -> version for telescope only (no DUT) works
    • Works with new (GEAR) alignment scheme
    • Adding DUT should be straight-forward -> track finding might be more difficult
    • Newest version GBL 2.0.X is included (using EIGEN instead of ROOT)
    • The new installer will check this out!

 

• EUDAQ2 readiness
  • Need more manpower to do this
  • We'll need it around summer (according to EUDAQ developers)
  • Yi took some data -> anyone working on EUTelescope reconstruction?
    • Edo: telescope only data can be reconstructed only changing the data converter
      --> Can we handle the merging of different data streams from different DAQ systems
    • Yi/Edo: present how EUDAQ2 works and how the data taking w/o mini-TLU worked
  • Developers workshop? At least Tobias, Andre, Yi should be available --> date?
  • Yi is taking data with FE-I4
  • EUDAQ2 based on certain version of LCIO -> EUTelescope would need to change to this version

 

• Radial strips
  • Alex' GBL code used for 2016 reconstruction (straight strips)
  • 2017: radial strips, Ryan to implement in TGeo -> want working reco after May
    • How to do the implementation?
    • To be tested in ALLpix
  • Andy/Kenny to open a ticket on the github issue tracker to start the discussion
    • Describe setup and structure of data
    • Will try to converge on a todo list
  • Who will work on this? --> Mail to Ingrid for manpower
  • Strips meeting 25/26.04. --> will discuss there, incl manpower
    --> report at our next meeting

 

• AoB
  • Next meeting May 22nd, at 10:00
