Minutes
Attendees: Igal, Jared,Thomas B.,Phil,Zisis,Susan,Jon,Sasha,Liping,Jane,Bill B.
- Thomas demonstrated changes to MCWrapper-bot, the web interface for submitting simulation jobs to the OSG, for JEF projects
- There is now JEF button, which sets the mc_JEF MC variation and fixes beam conditions
- For now we should use run number 90000, for which the database has been filled with the FCAL-2 geometry
- Recommended to submit jobs in blocks of events that are not too large (<1 billion, 250 M or 500 M okay, but Thomas would like a heads-up if submit large blocks like this)
- Latest batch of SICCAS crystals have been shipped to the lab (but not arrived yet)
- When the crystals arrive, will go through visual inspection (Sasha and Josh are preparing the clean room for their arrival)
- Received 20 new light guides; polishing looks improved compared to first batch
- Sasha and Josh working with Nick S. to update the temperature control for the brazing
- Will start construction of next set of modules soon
- Sasha contacted Carl Zorn regarding his light transmittance measurement setup: appears to be working, still need to work on paperwork
- Josh will make a replica of the setup used to study the crystals in the PS setup in the hall
- CCAL moved to the floor, plan to move the TEDF for refurbishment (bases)
- Divider design: waiting on Vlad P. for finalized tweaks
- Zisis working with Drew W. from the detector/imaging group to find a way to get dividers to Regina
- Tim B. still hoping to get LED driver, some bureaucratic issues need be resolved
- We discussed having slots for JEF talks at future GlueX collaboration meetings
- We decided to add space in the JEF meeting agendas for further discussion of studies using the current GlueX data, including 3π0 background
- Liping brought up plans for a white paper for the Snowmass project: there is some motion toward forming a working group with both theorist and experimental input -- what do we need from the theorists? Some other questions:
- What else can we look for using GlueX/JEF setup?
- What decay modes for the Dark Scalar should we study?
- Can we use beam polarization?
