Amy Sy

   Previous 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.

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.
