Commissioning Schedule and Shifts – First Call E906 Collaboration Meeting 23 February 2010

2 Commissioning  Understand Beam  Check detector gains and thresholds with minimum ionizing particles  Set detector timing  Set trigger timing  Measure rates in a systematic way – multiple KMAG fields ???  Take data to align spectrometer – KMAG magnet on and magnet off??  Take data to study trigger matrices  If STA 1 chambers exist, measure solid in center and at ends of liquids to help calibrate vertex resolution – Do we have an alternative??? Is there any usefulness for a cosmic ray trigger – air showers? How much time is need for each step? How much access time is needed for adjustments? What can be interleaved? What installation can be interleaved? Set up a commissioning plan group! Send us your requests – conditions, time access

3 Shifts  When do we want to start scheduling shifts?  One philosophy, start early and shift people will help in installation  Second philosophy, wait until we are ready for beam  Since 2 people will be needed for any NM4 access, will have to start with at least 2 once NM4 is closed up.  Need subsystem experts continuously available at FNAL early June??? until shutdown.  Nominally ~50 people – need 7 per week minimum– Given schedule conflicts probably need to start at 5-7 days/month of shifts for everyone.  We need lots of people around May-July  Get your safety training up to date, especially radiation safety and controlled access
