Present: Stepan, Maurik, Nathan, Matt, Tim, John, Raffayel, Bryan, Marzio

  • Expert on-call shifts (Stepan)

Stepan presented a table with expert on-call shifts, including run coordinator shifts, distributed among different institution. 


  • Status of the hodoscope construction (Rafo) 

Hodoscope construction is progressing well. Fibers are glued in PMT adapters and have been polished. Assembly of scintillator layers is complete as well. The next step is the final assembly on the frame, on the flange. Unfortunately, during the tests, one of the PMTs was broken. Fortunately, there is a spare from Hall-B BOM that can be used before the replacement will be purchased.  The full assembly will be done by the first week of March.


  • Status f the SVT upgrade (Tim)

The vendor sent 12 out of 20 sensors. Unfortunately, instead of cleaning only a slim edge, they used nitride on a larger area. That will be fixed by gluing an Al-foil (20-30 um), additional work. During the module assembly, it was found that longer pigtails are needed for L0, while for L1 they can be shorter, so for L0 modules that will be used for L1, pigtail has to be shortened.  

  • Simulations with 2019 detector (Maurik)

 Not much progress on MC, although tests are ongoing to finalize the setup. 


  • Status of 2016 data processing (Rafo)

Rafo reported that 60% of the data are now processed. Last week was very productive for HPS on the JLAB farm. If it stays that way, he expects 10-15 more days to complete the processing.  About 5-10% of jobs failed and will need to relaunch them after everything is done. The full completion of processing is expected by end of March.

At the end of the meeting, there was a long discussion about track-ECal cluster matching and cluster position corrections. More work will be needed to understand some of the odd distributions seen in data.
