- Talks at the Collaboration Meeting (Draft from last week)
- Fcal (Matt)
- UofR work (Zisis)
- Monitoring (Christina if available)
- USM update on SiPM and light guides- (Hayk will prepare)
- Update from Athens
- Gluex-doc-2052 First bunch of 1000 BCAL LED miniboards
- First 20 strings (200 LEDs) were shipped and received by JLab
- Data statistics on the first 1000 LEDs were shown including stability
- First 500 boards have been grouped according to intensity
- Elton: Please send the data electronically. [Note: Stratos has already shipped the files].
- Zisis: When will a schedule be shown for remaining deliveries? Christina should do this next week.
- Simulations
- BCAL Simulation (David L.)
- Goal is to add realism into the simulations in response to showers.
- Ready to make the updated code the default simulation
- Questions still remaining: effect of reconstruction and dark hits on resolution
- Elton: When will Andrei be able to provide more realistic input for the shower simulation? Andrei: Having some problems with fitting and extraction of parameters. Will provide an status update at the next meeting. Also work continues on spectra obtained with the fine-grained calorimeter.
- Update from USM
- Status of testing at JLab
- GlueX-doc-2053 Tests of pre-production readout assembly on mini-Bcal
- Measurements of new pre-production boards on the mini-BCAL show that they will be acceptable to the experiment.
- Write-up of studies is underway and will be made available later this week for feedback.
- GlueX-doc-2051 Cross talk and after pulsing (Ivan)
