BHCal Meeting 2026-09-25
General
- Rehearsal in two weeks
- Three sectors
- Purchase of tiles
- Performance
- Charge attached to last week’s review agenda
Jan: calibration
- At low energy, distribution of cluster energy sums doesn’t show a clear peak, which is visible in distribution of hit energy sums
- Points to losses in clusters
- However, thresholds are implemented in both hits and clusters, so cause is unclear
- ACTION ITEM (Jan): plot hit energy vs cluster energy distributions (not sums) to check how thresholds compare
- ACTION ITEM (Anjaly): what is sPHENIX tower threshold? (is it 20 MeV?)
Hardware update
- Highway still out of commission
- Moved everything up to Hcal lab
- KCU unit programming apparently not working right now
- Need input from Norbert
- New CALOROC board should come soon
Churamani: HCalTruthCluster study
- We understand now what these Hcal truth clusters are
- In DIS events there are some effects that are probably caused by some issues in this simulation campaign, which should be fixed in the latest campaign (August)
- Plan is to move on to ML based calibration next
There are minutes attached to this event.
