• Are analyzing previous data and ready to start taking data in October

• Hytar Correlation with Theta (Julette Crowder)

• Showed results of HMS pointing survey
• Showed off sets for different runs
• Showed strong correlations between these offsets and survey data

• Zeidman He (e,e'K+) (Howard Fenker)

• Went over a list of issues from mini-readiness review
• SOS magnet should some how be interlocked to beam
• 90% of the DAQ work involves Steve Wood. Steve says he is o.u. with that
• Release the trigger points on iron chambers
• List of people for shifts for exp. target
• Training needs to be up to date before going on shift

• HNSS update (Liguang Tang)

• The second meeting on beam energy stability test will be hold on 9/23 and we will discuss and draft a test plan;
• All SSDs have been ready for assembly and they are in Houston. Person will here carry them since shipment seems damaging some of the wire bonding. All damages due to shipping from Japan have been repaired and the noise level is an order of magnitude lower further thus very low.

• BCI gives 1% absolute beam current measurement time
• BCI electronics overview

• Comments (Roger Carlini)

• Planning to make an offer for the Hall C staff position
