Amy Sy

- 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 (Aug - Sept )
- Isotopes –Attended several planning meetings. Setup some equipment needed for next week’s run
- ARDDOT - Had a few meeting with the Injector group to determine if the new viewer image design would work for them. They have some
very tight spaces. Met with the I&C group to show them the viewer imager and to test a lipstick replacement camera. The tested camera
has an nonadjustable lens an images a lot of the tube with a small image of the view screen. Not sure that it is a good replacement. The
I&C folks had to run to another call and didn’t have time to assemble an imager. We will reschedule for another time. Have inventoried
and conveniently placed all the parts received for the imager. Still have a few parts including the cameras that have not arrived.
Next two weeks (Sept 14 - Sept 25)
- Isotopes – Help as much as possible with the upcoming experimental run.

Andrew Hutton
Previous two weeks (Aug 31 - Sept 11)
- I attended various EIC meetings. I also spent some time studying the draft report from the Alternate Strong Cooling Task Force. This resulted in a suggestion to Geoff
and Fanglei to shorten the high energy section of the dual ring cooler; I sent the same recommendation to Jorg Kewish for the single ring cooler. I proposed a method to
arrange the cross-over between the high and low energy sections of the dual energy cooler using twin-axis SRF cavities. Finally, I suggested to Jorg that he modify the
wiggler design he developed for the single ring cooler to be compatible with the high energy section of the dual axis cooler ring.
- The modified (and much improved) PERLE ICRADA was sent to the DOE.
- We have been making detailed plans for the Isotope Irradiations, scheduled for September 13 - 19.
- I have been active on the AWLC 2020 organization, proposing three talks from Jefferson Lab, which were accepted.
Next 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.
- 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.
