Max Bruker

  Previous (Sept 14 - Sept 25)
     - IBIC
     -	UITF fun. Run 1 ongoing; beam delivered to HDice with successful alignment to the IBC solenoid axis. Massive intermittent problems with energy jitter from SRF booster 
       microphonics. After nailing down a "golden orbit", the objective will be to provide further support for Rogowski BPM studies and tests of the raster system.
     -	Cooling simulations for the IMP paper. Discussions are ongoing.
  Next (Sept 28 - Oct 9)
     - UITF run 1 finished. The energy jitter issues seem to have been mitigated. QSUtility scans for optics verification and emittance determination were partially successful. The
       "golden orbit" is supposedly known at this point, but reproducibility of the chicane axis continues to be a problem despite diligent hysteresis cycling. It could be caused by
       day-to-day variations of the beam energy rather than the dipole fields. With the exception of minor issues, the beam line is looking OK; however, the BPM studies were not 
       spectacularly conclusive, and the raster system is underperforming. The HDice folks are trying to come up with a synchronization scheme that will partially blank the beam to
       mitigate the inhomogeneous illumination pattern.
     -	We seem to be in agreement on the parameters for the cooling simulations. He Zhang finalized the simulation data. The draft of the manuscript was updated accordingly but is
       still missing a short comparison of the jitter-induced heating rate with theory.
     -	Some thoughts about RF/beam feedback simulation.

Amy Sy

   Previous two weeks (Aug 31 - Sept 11)
     - Completed August 2020 EIC Design Update Newsletter.
     - MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Working on solutions that match to the existing optics for both
       solenoids.
     - Attended various meetings on second IR-related topics.
     - Attended closeout session of DOE OPA status review of EIC.
   Next two weeks (Sept 14 - Sept 25)
     - 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.

Joe Gubeli

   Previous two weeks (Sept 14  - Sept 25)
     - Isotopes –Attended several planning meetings. Created several simulations for shell and tube heat exchangers to test the effectiveness of various designs. These various
       parameters that were modeled were the number of coils, the bend radius, flow rates for both the gallium and water, tapered coils and the relative orientation of the coils. In
       total sixteen simulation were ran with the best performance to the models that had the gallium coils perpendicular to the water flow. Worked with Steve B. and Kelly T. on the
       as-found and ideal location of the last isotope dipole. The dipole needs to move approximately 10.1 mm in X and 29.5 mm in Z to shift into the ideal position. Spoke with Neil
       W. about how this could be accomplished without removing the vacuum chamber.
     - ARDDOT - Assembled all the viewers for which I had all the parts. A total of seven are ready to install with the remaining needed to wait till early November when the
       remaining parts are expected to arrive. Sent the three ARC 7 SLM stand positions offsets to S&A to convert into machine coordinates. Met with Neil W. on the work required for
       this task.

Andrew Hutton

   Previous two weeks (Sept 14 - Sept 25)
     - Isotope Irradiations took place Sept 13-16.  This involved a stack of Nickel and Vanadium foils and isotopically pure Gallium71 in a powdered oxide form for calibration.  We
       also irradiated a solid graphite block to obtain approval for using graphite as the crucible for the later irradiation of natural liquid gallium.  We obtained approval the same
       day (actually after hours in the evening) and irradiated the gallium for a total of 26 hours.  The LERF was not being cooperative and we lost 12 hours to an RF station, but 
       because of the rainfall from the SALLY remnants, we were able to extend the run (too dangerous to remove the shielding blocks).  The results appear to confirm the FLUKA results
       for Gallium, but we are pretty sure that FLKA gives the wrong results for Nickel (one of the daughters has twice the production rate, the other one half).  We are still having
       meetings to get all of the calibrations correct in view of a publication.  
     - Lila presented the work she did at Jefferson Lab as an REU student at the "The DOE Isotope Program’s Virtual Seminar Series: On the Horizon: Novel Isotopes and Future Leaders.”
       I worked with her to make sure she did well.  
     - I spent a lot of time looking at the harmonic kicker for the EIS RCS; in my opinion, too much effort has been spent on optimizing the RF to avoid problems that I do not believe
       are problems.  I prepared and presented a talk on simplifying the harmonic kicker design for the EIC.   
     - We received preliminary approval for the PERLE ICRADA from the DOE - submitted on September 3, pre-approval obtained on September 23, faster than it took to go through the 
       system at Jefferson Lab.  It required two Jefferson lab signatures, Andrei and Drew; both have signed.  Now it goes to IJCLab where Achille Stocchi, the Director, is eager to
       sign it. 
     - There was a VNECA meeting scheduled and I read through the draft Governor’s Statement in preparation.  My suggestions from the first draft had all been incorporated and I 
       actually found a typo in the latest version (the authors were delighted!).  The meeting was postponed at the last minute.  
   Next two weeks (Sept 28 - Oct 9)
     - EIC:  After giving a presentation on there harmonic kicker, I updated my ideas and sent them out in an email.  I received no feedback!  I also attended the EIC Collaboration
       Meeting which was actually considerably better than I had anticipated.  I attended the EIC Collaboration Meeting dry runs and then the Collaboration Meeting itself, which was
       actually considerably better than I had anticipated.  
    - Isotopes: we are still trying to understand the irradiation results, and have had several meetings to clarify things.  In parallel, we are continuing design work for a 50kW 
      target.  The latest idea from Pavel Degtiarenko is to use an external heat exchanger and pump the liquid gallium around with a magnetic pump.  So far, the idea looks better than
      our previous design.
