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. Next two weeks (Nov 25 - Dec 6) - Continue working on EIC project

LERF - Steve Benson
Previous two weeks (Nov 25 - Dec 6) - Assisted in run to the 1G dump with CW beam. Unfortunately we could not run beam. - Reviewed SBIR - Reviewed IPAC 2020 abstracts - Looked over new Phase II SBIRs - Met with diagnostics team to derive a plan for replacing the beam-a-nizer frame grabber at the LERF - Met with the magnet group and came up with a strategy for the kicker coils for RF merge test - Continued gathering documents for the ERR punch list - Planned for another run to the 1G dump Next two weeks (Dec 9 - Dec 20) - Assist with the run to the 1G dump - Certify User Lab 4 in the LERF - Host Michael Famiano for Acc. seminar (with Joe Grames) - Move excess equipment out of the LERF
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.
