GENERAL
- No Barrel HCal meeting next week as ePIC Collaboration Meeting is ongoing.
- Future meetings will resume at 9AM due to the preferred timings from many.
TDR STATUS
- Stefan and Murad have made changes according to the comments received. Most of the edits are made. Figures and their captions need to be reviewed.
- Overleaf to the TDR: https://www.overleaf.com/project/667588746c6114e26ddbced3
- Reviewed the figures from TDR:
- Figure 5 needs to be updated (current one is probably from Run 23)
- Figure 7 is a duplicate (remove this one)
- Figure 8 (taken care of )
- Figure 9 and 10 — good [Fig 9 with only BHCal, Fig 10 with full ePIC detector simulated]
- Fig 15: good (caption does not distinguish the panels)
- Fig 16: Add more text on this, increase the size of the fig, Consider to crop and put the third figure below to be able to increase the size.
- Fig 17: good
- Fig 18: good (Murad raised the question, why is the JES-1 is momentum resolution? There is a typo: replace ECal to EMCAL)
- Fig 16, 17, 18, —placeholders
- Olaiya had updated the figure including the E=20GeV. (This feature is still under investigation. Leave this comment for reviewers)
- Stefan pointed out—In new figure, below 0.2, there are data points which were not there before—Should we update the figure now?
- Derek: New simulation with better geometry (post GDML)
- Jump at lowest energy is not understood,
- Olaiya would make the new plot with all the added energies and cluster cut and the new plot will be added in the next iteration.
- Previous figure had a cut of ‘requiring non-zero energy in the HCal to improve the training statistics.
- Decided to keep the old figure for now since we don’t understand all the features of the new one.
PROTOTYPE STATUS AND PLANS
- Use RCDAQ in VNC for the test stand at hcal lab as it helps for coordination.
- Anjaly will put together some more information to the slides that Eric sent around.
- As of now, 4 SiPMs are back to functional after Martin Norbert, Stefan and Anjaly spent a few hours on Tuesday debugging as Eric had difficulty getting the signal this week.
- Eric: Should we reorder 120 SiPMs for the prototype as the reverse polarity fix is not ideal??
- Steve offered help with this if needed.
- Martin and Norbert worked on getting TOT and TOA distributions and codes were updated to the roc_analysis directory.
- Martin worked with Olaiya to get the setup at NH functional.
- Martin’s request: Leave the hcal lab setup alone during Wed and Thur next week.
- Stefan met with Eric and his students last week on arranging the tiles on the prototype in high bay.
- Norbert : Consider alternative connectors like MCX connectors for the ePIC Barrel HCal.
- Steve will take lead on comparing the connectors and see what is the best one w.r.t cost and efficiency.
SIMULATION STATUS AND PLANS
- Derek: Working on updating and correcting the place holder figures.
- Murad raised his concern on the bug in the GDML file and how we approach this. (Needs further investigation)
