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)
- Work on Bob's RF issues

Bhawin Dhital
Previous two weeks (Oct 26 - Nov 6)
- I was working on momentum aperture and Touschek lifetime calculation in dual energy storage ring.
- We are using our own python script to calculate momentum aperture in dual energy ring. This code printsout the maximum momentum acceptance value for each
machine element. Dr. Fanglei Lin has written the python code for it and I am trying to understand and implement it in our system.
- I have presented the status and update on dual energy ring cooler in EIC meeting at Jefferson Lab on Nov 06. Dr Douglas Higinbotham asked me to present my research
in that meeting as I got the EIC fellowship 2020.
Next two weeks (Nov 9 - Nov 20)
- I will be working on momentum aperture calculation in dual energy storage ring. We came to know that the momentum aperture in high energy ring is smaller than the
momentum aperture value in the low energy ring. This is limited by the SRF cavities we use to accelerate the beam energy in high energy ring.
- I will be editing the tech notes written on dual energy storage ring. When editing completes, It will be sent to JLab online system.
- Calculating Touschek lifetime analytically and using elegant simulation.

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 26 - Nov 6)
- EIC: I attended meetings, including the Editorial Board, as well as the Review. The editorial activity will probably greatly expand in December.
- 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
Next two weeks (Nov 9 - Nov 20)
- EIC: again, I attended meetings, including the Editorial Board. I provided feedback to Bhawin and Fanglei on how to calculate the Touschek lifetime in the two energy
cooler - resulted in doubling the lifetime!
- Isotopes: We have made excellent progress on preparing the documentation for the ERR as well as building new hardware. Kevin built a new raft, Adam Stavola has made
progress on getting pieces for a coincidence measurement of an aliquot of the irradiated gallium (Joe did the 3-D design and the Detector Group built us a beta detector). I
think we will be able to submit the documentation for the ERR by Thanksgiving, on schedule for the ERR December 14 (the 11th is the back-up date), which Camille is setting up.
I also attended another virtual seminar organized by the ONP Isotope program - mainly on chemical separation which was not too interesting for us, but I need to support our
Program Manager!
- Photon Source Working Group: I sent feedback to Steve, suggesting some basic first decisions. Hopefully, he will bring them up.
