Kondo (chair); Matt, Klaus, Marcus, Tom 

Progress at BNL (Bob, through e-mail)

  • Provide the FNAL Test beam update.
  • They completed a scan of the multi-ZZ pattern PCB, along with gain and gap field scans.
  • Have other ZZ boards we want to test as well, including micromegas based detectors with ZZ readout.
  • Overall things are going well. They will report more in two weeks.

Progress at FIT (Marcus)

  • They receive the new longer screws, will prepare them (cleaning etc ...) for assembly.
  • Will put the mock chamber together once more this week to check if gas leak issue is fixed with the longer screws

Progress at INFN Trieste (Silvia)

  • Forgot to alert Silvia about the summer time changing in the US. She called in an hour later after the meeting was already adjourned

Progress at SBU (Tom)

  • Working in progress for the TPC prototype
  • Interesting progress on the picoammeter they purchased for the TPC Ion back flow measurement. The device from PicoLogic (Zagreb, Croatia) comes with a LabView software for the readout.
  • Not convenient for integration into the RCDAQ software used by the group. They succeeded to implement the command of the picoammeter in Lunyx in order to interface it with RCDAQ and to control it through Linux Shell command.
  • Characteristic of the can be found at http://www.picologic.hr/files/info.pdf and more detailed description in the NIMA paper http://dx.doi.org/10.1016/j.nima.2015.08.021

Progress at UVa (Kondo)

  • Not much to report. The fabrication of low cost frame in the local machine chop turns out to be longer than foreseen => expect delivery this week and start gluing the parts of the frame together
  • Good progress on the CAD drawings of the mechanical stretcher plate for the EIC prototype by (Grad student John Matter. We will refurbish existing plates and stretching parts to save cost.
  • Plexiglass plate usually used as assembly GEM support plate will be replaced by the more expensive 1 m^2 Teflon plate to address a potential problem during the gluing of the frame to the GE foils because of a flaw in the original design of the common GEM foil.
  • Marcus asks about whether I already identify the student to replace Siyu for the eicROOT simulation work. Answer is not yet. Will check with Nilanga about new UG students interested in the project.

Progress at Temple U. (Matt)

  • The group is planning to build a third FGT triple GEM prototype (the second with Kapton ring spacers).
  • In the process, they will try to understand what went wrong for the first two prototypes with high leakage current that stop working after a few days of cosmic
  • Assembly of this prototype will likely start in April due to the commitment of Postdoc Amilkar busy as run coordinator at BNL


  • Kondo reminds of the request to contribute to the tracking section of the "EIC Detector Requirement and R&D handbook".
  • Marcus summarize the goal of the the document which is meant to contain the detector requirements for the EIC and the different technologies currently under consideration to satisfy these requirements. It is not designed to be a detailed description of the R&D that we are conducting for the EIC detector.
  • Marcus raises the question of the merger of eRD3 and eRD6. The question was whether we wanted to merge eRD3 and eRD6 into a new consortium with a new eRDXX or eRD3 (basically Temple U.) integrate eRD6.
  • There seems to be a general consensus that the the integration of eRD3 into eRD6 is the best solution for practical reasons and the name recognition as well.
  • Bernd and Matt will take care of the Saclay part of the integration
