1. Announcements
   • GlueX Collaboration Meeting May 23-26 (Mon - software/tutorials, Tue-Thu)
   • Shifts/RCs. Aleandre Deur has volunteered to serve as RC for the first two weeks.
   • Run Coordinator Meeting for CPP will start in the next 2-3 weeks and increase in frequency as we get closer to beam
   • Congress has passed the funding bill but JLab is still operating under a Continuing Resolution (CR) until funds are distributed.
   • Accelerator beam energy is expected to be about 11.6 GeV
2. Action Items
3. CPP-NPP Trigger (Sasha)
   • Beni: Sasha has been in contact with Hai and they are in the process of uploading the TOF trigger firmware into the hardware. Ben Raydo has been contacted to assist with any changes to the global trigger configuration.
   • Sergey: Pulser data has been used to produce run R 100,068. He would like us to run the monitoring histograms on this data to verify continuity.
   • Beni: The new translation table (text file) is available from Justin, but has not yet been loaded into ccdb.
   • Alex: Promised to send out a message with instructions on how to use the text file. [Note added: See email from Alex
