Meeting time and location:

Agenda

ECAL maintenance and performance during the run
- HV module disconnected from the EPICS control
- Bad flash ADC for reference PMTs
- Low-level histograms [1]
- Adjusting high voltages [2] (based on the run period 10, iteration 0)
- Recent ECAL occupancy, production at 300 nA with 4x10^-4 X0 Al radiator [3]. Suspicious modules after the accelerator maintenance day
Calibrations
- Initial HV settings using Compton scattering events [4]
- Pi0 calibration page [5]
  - Pi0a are clearly seen for most ECAL modules (except the innermost ring)
Monitoring
Restoring PS test setup [6]
- The prototype has been assembled and tested. Ready for installing in Hall D
  - Move it to the Hall on Wednesday next week (?)
