1. Notes from the past 24 hours
   • Accesses
   • MCC reported minor issues with RF separators last evening
   • Collected about 1.6B triggers on full target
   • beam position was relatively stable
2. Issues
   • CCAL HV module replacement, previuos (good) run might be affected, periodical autoreset of occupancy plots could help
   • DAQ rates scaler still frozen, DAQ rates scaler back after restarting trig_client
3. Reports
   • Rate monitoring
   • beam energy monitoring
   • AC y signal decay follow up
4. Today
   • Production running, 200nA, 10^-4 Al
5. Run Plan
   • Beam studies on Monday full 8 hrs. RF recovery if needed.
   • End of run in two weeks time...
6. AOB
