Max Bruker 

  Previous (Oct 12 - Oct 23)
     - Took a close clook at Gang Wang heating. We understand most of the math and underlying assumptions now.
     -	My tracking code that calculates the space-charge kicks during bunched cooling now uses a 3d charge distribution instead of the 2d one we used to work with. The 
       result is closer to reality and allows us to look at both transverse instabilities at the same time; however, the penalty in terms of computing time is
       unsurprisingly massive.
     -	The results from the first two bullet points are in reasonable agreement (factor of 1.5).
     -	All of this has been incorporated in the revised manuscript for the IMP experiment. The current version addresses all comments made by the reviewers. It is now 
       being circulated; I do not expect any major revisions at this point.
  Next (Oct 26 - Nov 6)

   Previous two weeks (Oct 12 - Oct 23)
     - Submitted input to EIC Biweekly report.
     - MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Integrating the quadrupole and skew quadrupole fields into the 
       solenoids
       can potentially save ~10 m of space per solenoid, for ~20 m total. Solutions matching to the optics while zeroing out the coupling parameters beta12, alfa12, beta21, and
       alfa21 using PTC_TWISS in MADX were very difficult to find when dispersion constraints were also included in the optimization. Preliminary solutions for both solenoid
       modules were found by relaxing the horizontal dispersion and dispersion prime constraints on the match. The coupling parameters are about an order of magnitude larger than
       in the original lattice, and further work is needed to study the implications of this on the beam dynamics in the spin rotator.
     - Attended meetings on revisions of the IMP experiment paper.

     - Collected and edited inputs to the September 2020 EIC Design Update Newsletter.
