o LVDT calibration surveys for the HRSr will be performed
  before the experiment starts.  This will probably require
  five surveys - small angle, large angle, three intermediate
  angles.  The LVDTs will not be of use for the HRSl since
  it is static throughout the entire experiment.  We will 
  rely entirely on survey for its location.

o lockup may occur as early as Monday morning.

o BR reviewed the shift schedule and showed the holes we 
  have, particularly early on, which are worrisome.  He made
  arrangements to cover these places with various people.

o KF laid out the runplan and we addressed the nagging questions
  that we had been putting off.  We are taking collimator in/out
  data in parallel kinematics.  We also decided to split kin_a+
  50/50 collimator in/out.  Between these two data sets we should
  be able to decide if we see any collimator-induced effects,
  and we'll adjust as appropriate.  We anticipate none and 
  thus will probably run collimators out for all of the production 
  data.  KF will put together a release-version of the detailed 
  runplan over the weekend.

o XJ presented his request for beamtime.  To summarize, he would
  like 1.0 shifts evenly divided between Pmiss = -140 MeV/c and
  Pmiss = +140 MeV/c measure ALT and RLT for 12C.  We will consider
  this if we get off to a very good start.  We are not sure if we
  are allowed by the lab to look at another target for physics.  
  Decision postponed until this is known.

o MA reported on his progress with the .tcl scripts.  DH will get 
  together with MA and doublecheck things.  He suggested to start 
  with the E98108 scripts and make modifications.  We need to add 
  the OTR variables and the H2Ofall variables, for example. 
  
o WH reported on her progress with the online analysis software.
  The detector kumacs are in place.  She is currently putting 
  together the physics ESPACE and PAW kumacs.  They are about 80%
  complete.  Some modifications (from left and right to electron 
  and hadron, for example) still need to be done.

o DM reported on the H2Ofall target.  He outlined the target ladder,
  the thicknesses of the (hyperpure) BeO and (pyrolytic) 12C foils,
  and quickly went over changing targets and the various readbacks 
  again.  He has prepared an operations document that will be posted 
  to the E00102 website.

o NL went through his thoughts on how our QE 16O(e,e') optics
  checkout of the HRSr would be better performed as QE 16O(e,e'p)
  (punchthrough) optics.  He thinks an Emiss cut can clean up the 
  punchthroughs sufficiently that the information we need can be 
  obtained.  He pointed out that the negative polarity measurement 
  probably was just a waste of time, and that it would be better to 
  come up with the HRSr set for protons.  We agreed to go with this 
  suggestion.

o the general meeting broke up and KF, WH, LW, MA, and WH remained and
  went through the detailed runplan line-by-line.
