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.

aperture in a dual energy storage ring and we decided to go with our own code to calculate the momentum aperture for each machine element in the ring.

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.
Next two weeks (Sept 28 - Oct 9)
- Collected and edited inputs to the September 2020 EIC Design Update Newsletter.
- MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Continued optimization to reduce the magnitudes of the coupling
parameters and final quadrupole strengths.
- Attended the EIC Workshop on potential international collaborations.

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

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.
