River Huang
Previous two weeks (Nov 11 - Nov 22)
- Transparent Spin Projet - In order to test the theoretical prediction, we introduced different cases of misalignments in RHIC lattice
configuration and we obtained the spin field direction and the resonance strength by fitting the data to offset spin curves. The
obtained resonance strength was consistent with the theoretical prediction. The spin field was close to horizontal as expected. We plan
to report these results on IPAC2000.
- CASA Beam-Beam package - In order to generate or deal with users’ own data for different phase definitions, we completed a Python code
and added it into CASA Beam-Beam package. We revised BeamBeam3D (BB3D) so that BB3D can track all detail changes of a particle phase-
coordinate.

Andrew Hutton
Previous two weeks (Nov 11 - Nov 22)
- Lost a fair amount of time due to (very) minor surgery, pre-op and post-op visits, etc. I will survive!
- On November 12, I attended a VNECA meeting on Richmond to approve the draft annual report (I sent a copy to Stuart, Andrei and Todd).
We are moving forward on closing out the Isotope ERR items; we will have had two meetings on this as well as a lot of behind the scenes
cajoling.
- I discussed with Doug Wells, our isotope collaborator at NMT, a new FOA for Isotopes which is only available to Universities. It was
agreed that NMT would take the lead on this. I discussed this with Stuart and got his blessing to proceed. Our part would be
irradiating targets prepared at NMT, which would then be shipped offsite to VCU for separation. Chemists from NMT would participate in
the separation. We also discussed the follow-on Isotope FOA that currently funds us; Doug will develop a short list of isotopes that we
could address, and we would then discuss this list with Ethan Balkin, DOE-ONP Isotope Program Manager, to gauge the level of interest.
We expect this FOA to come out in July 2020.
- I developed and presented my idea for asynchronous electron cooling for JLEIC. I now don’t think this is the best solution, but I was
pleased to generate discussion that hopefully will lead to improved understanding of the cooling process.
Next two weeks (Nov 25 - Dec 6)
- We hope to have CW beam to the 1G dump (credit to Kevin, Steve and Joe). I also hope to be able to submit demonstration that we have
met all of the ERR items and receive beam authorization for the first 1kW isotope irradiation.
- On December 3, i (and Todd) will be on a conference call to advise the Madison Accelerator Lab.
- I will continue to look at improving the JLEIC cooling.
