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)

Amy Sy

   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.
   Next two weeks (Oct 26 - Nov 6)
     - Collected and edited inputs to the September 2020 EIC Design Update Newsletter.

Andrew Hutton

   Previous two weeks (Oct 12 - Oct 23)
     - EIC: attended meetings but I didn’t initiate much; same for the Editorial Board.  I did spend time to write to Stuart to update the laboratory Plan, which he
       promised to do.  
     - Isotopes: a really busy time trying to make sense of the irradiation data and write up the Quarterly report. We have also spent time on the design of the 50 kW
       target (with Joe and Kevin) as well as upgrading the present raft to improve the cooling for 5 kW (primarily Kevin). Lila has been working with George Kharashvili 
       to understand how to search for “granddaughter’ isotopes of interest.  I start weekly meetings with her this week.  
     - ILC: I spent a lot of time preparing for the AWLC 2020 Workshop, where I ended up chairing the panel session on Lab contributions to ILC.  I also attended a large
       fraction of the talks.  
   Next two weeks (Sept 28 - Oct 9)
     - EIC: again, I attended meetings, including the Editorial Board, but don’t think I contributed much.  
     - Isotopes: the Quarterly Report was finally sent out and including a reasonable understanding of the irradiation results. We are now addressing the ERR
       documentation for the 5 kW irradiation, which we have promised before Thanksgiving.  The Review will occur at the beginning of December and the 5 kW irradiation itself the
       week of January 11-16. We will administratively restrict access to the GTS vault during the irradiation because of airborne radiation and ozone, both of which will be
       tracked for future irradiations.  This request has been agreed by Riad. 
     - PERLE: there was a PERLE Collaboration Board meeting, following which I had a discussion with the Achille Stocchi and a couple of others on the conditions that they
       would like for Jefferson lab participation. I sent Stuart and Andrei a synopsis of this so they could prepare our response.  
     - There was another meeting of the ALCC to discuss the outcome of the AWLC workshop and future actions, including how to support the ILC Pre-Lab.  I sent details to
       Stuart and Andrei.
