Minutes of the E89044 Collaboration Meeting

                   15 March 2000

----------------------------------------------------

09:00 Arun Saha gave a brief overview of the e89044
      physics program and the kinematics that we have
      completed.

09:15 Marty Epstein gave a more detailed report of the
      data that we have collected thus far.

09:40 Eric Voutier reviewed the physics of the e89044
      program.

10:05 Kess de Jager discussed the 4 TBD days.  
      The e89044 experiment used 1 day for 3He, 
      1 day for warm-up and survey, and 1 day 
      for Hydrogen measurements.  The last day 
      was used for energy measurements and some
      short tests of experimental equipment.

      Kees also discussed the labs eagerness for the
      e89044 experiment to present results.  Kees
      will be looking forward to Michael Kuss's report
      at the Gordon conference in August.

10:30 Nilanga Liyanage reported that he has written 
      a user friendly code to optimize the spectrometer 
      matrix elements.  Nilanga is willing to teach anyone 
      from our group how to use this code, but he does not 
      have enough time to optimize all of our data himself.

(Coffie Break)

11:45 Michael Kuss reported that he has checked the BPM
      information in our data and everything seems correct.
      He has rewritten an ESPACE routine (which we have been using
      on the ADAQ machine) which correctly accounts for the
      rastering of the beam.

      Micheal is now working on standardizing his code. 
      Once he is finished he will give his code to Ole Hanson 
      to become part of the standard ESPACE. 

(Lunch)

14:20 Marat Rvachev reported that the test Sieve Slit data
      we took with the dummy cell can not be used for
      calibration of theta and phi due to events punching
      thru the Sieve Slit.  We will be able to use the
      Dummy Cell data for checks of the target position.
      Also by looking at raster on and off, it can be
      used as a check of the raster correction.

15:05 Fatiha Benmokhta showed her analysis of Kin#14.  Her
      analysis of this LARGE data set (80 Million Events in total)
      shows that after analysis we will have approx. 50 events
      in the two body peak.

      Fatiha also showed that the second timing peak which appeared 
      when the electron arm was moved to large angles was due to pions.

15:35 Douglas Higinbotham presented an outline for the data analysis.
      The various aspects of the analysis he felt need to be addressed
      are as follows:      

     (1) Target Thickness Analysis
         0 Elastic Scattering Data
           645 MeV 1-5 fm^-2
           850 MeV 1.3, 1.9, 5.0, 15, 19 fm^-2
           1254 MeV 5, 15, 19 (11) fm^-2
         0 Luminosity Monitoring Data
     (2) Monte Carlo (MCEEP)
         0 Calculation of Solid Angle Acceptance
     (3) Standard Analysis Tools
         0 Radcor
         0 Allfit
     (4) ESPACE Data Analysis
         0 Raster Correction
         0 Energy Loss Corrections
         0 Calibrations (i.e. shower calorimeter)
         0 Optics and Header Files

     An understanding of these items is essential to being able to
     extract accurate cross sections from our data.  

After the meeting, we were all invited to Arun Saha's house for
a collaboration party!

The next e89044 Collaboration Meeting will be held on 14 April 2000.
This meeting will be devoted mainly to reviewing what we have measured
and how we are going to analyze it.
