Previous (Mar 16 - Mar 27)
- Started writing the PRAB article about the IMP experiment. Some questions are still unresolved, but the quality of the
results is starting to look convincing nonetheless.
- Remotely attended the first UITF training session
Next (Mar 30 - Apr 10)
- Continue and hopefully finish my part of the article. There is not much left to do as far as the longitudinal and transverse
profile data are concerned, but I'd like to understand what happens to the synchrotron frequency. Also, I'm getting the
impression that nobody quite knows what our objective/conclusion is supposed to be. I hope we'll figure it out along the
way.
- Attend more UITF training and hopefully the communication seminar that keeps being postponed.

Previous two weeks (Mar 16 - Mar 27)
- New model added to JSPEC, which allows to use multiple electron bunches to cool one ion bunch. The electron bunches are
assumed identical but placed at different positions. Kick due to the raising/falloing edge of a cylindrical electron bunch
is
added into the turn-by-turn model.
- Did some calculation/simulations on eRHIC low energy cooling.
Next two weeks (Mar 30 - Apr 10)
- Non-magnetic friction force formula to JSPEC. Heating effect to JSPEC.
- Keep documenting JSPEC.
- Perform simulation on IMP experiment if data is available.

Previous two weeks (Mar 16 - Mar 27)
- The last two weeks have been spent trying to get used to working from home. I think I am getting there!
- For the EIC, I attended two meetings of the RF team, I wasn’t much use. I did spend a fair amount of time to look into the
idea of reducing the vertical emittance in the EIC proton ring, either by emittance exchange or coupling. For the emittance
exchange,I am now certain that the “traditional” method of transverse-longitudinal coupling will not work for 25 GeV protons.
I do believe that a transverse emittance re-distribution might be possible, either in the transfer line or in the Yellow Ring. Of
these, the transfer line would be best. I also think we could look into slow extraction from the AGS followed by horizontal
stacking in the Yellow Ring.
- For the Isotope Program, I have been involved in suggesting directions for calculations which are proceeding well (Joe
Gubeli and Keith Welch, aided and abetted by the NMT students). I have prepared a new set of milestones and sent it round for
comment - so far it is an anechoic chamber out there! I also sent around information on the upcoming FOAs and got a positive
response from Jamal at VCU, but Doug Wells has been offline for weeks. I suspect he has been dragged into organizing teaching
online, a massive task!
- I attended a videoconference on PERLE which is starting up again. I wrote up a brief report fro upper management, with
positive response from Andrei.
- The ALCC is now considering writing a short White Paper to submit to the Snowmass meeting November 4-6, 2020 in Fermilab. I
will probably get involved editing that.
Next two weeks (Mar 30 - Apr 10)
- Continue with EIC work, hopefully collaborating more closely with Dave Douglas.
- I will need to finalize the Isotope Milestones and send them to Ethan Balkin. I also need to write the Isotope Quarterly
Report, due around April 24.
