  Previous (Nov 23 - Dec 4)
     - Haven't needed to do UITF shifts so far. There were some issues with the target, and Cebaf staff has been helping out with shifts as well.
     -	The copyediting process of the IMP article is in progress. The results have been unsatisfactory so far. I hope to understand why the process is designed the way it is and
       ultimately change it or at least improve the documentation. The way it currently is, publishing a decent-looking and standard-conformant PRAB paper is impossible.
     -	Regenerative BBU studies. I'm trying to use "bi" to simulate it.
  Next (Dec 7 - Dec 18)
     - UITF shifts maybe
     -	More BBU and other RF studies

   Previous two weeks (Nov 23 - Dec 4)
     - Momentum aperture and Touschek lifetime were calculated in a dual energy ring with two set of energies, low energy ring = 150 MeV and high energy ring = 500, 1000 MeV. The
      calculated lifetime are couple of hours. Touschek lifetime were calculated using elegant simulation and using analytical formula. However, there is some discrepancy of 
      calculated lifetime especially in high energy ring.
     - I was working on tech notes on dual energy storage ring. About 6 tech notes were prepared and edited.
   Next two weeks (Dec 7 - Dec 18)
     - I will be working to figure out the discrepancy in Touschek lifetimec calculation in a dual energy storage ring.
     - I will complete the tech notes.

Andrew Hutton

   Previous two weeks (Nov 23 - Dec 4)
     - EIC: I attended meetings, including the Editorial Board.  
     - Isotopes: This was a major effort over the last two weeks.  All of our documentation was submitted a week before the ERR, as promised, with the exception of the RSAD 
       because Keith Welch had to have a retina reattachment.  Joe has done an excellent job of calculating that the target, raft and crucible are thermally stable, and Kevin has 
       finished building these.  On the other hand, the beam window was calculated and recalculated by Joe, always resulting in producing window failure.  Thermal management was the
       subject of an Engineering review by Dave Meekins and Tim Whitlatch, who agreed with Joe’s calculations.  I contacted ANL-LEAF and was able to negotiate a loan of a window that
       has taken up to 500 µA, three times higher than we need.  We have to arrange to have it shipped here and installed before our run on the week of January 9.  I also have made 
       progress on two talks I have to make to the ERR Committee on December 14.   
     - PERLE: There has been some movement on PERLE, with an email from Achille, which prompted a response from State and Andrei.  They are trying to arrange a videoconference 
       before Christmas. 
     - I made some (helpful?) suggestions to Amy and Edy on their long proposals for the early Career Award, assuming that they will be invited to submit them.  
     - Funds: We are waiting for a decision by the DOE-ONP Isotope Program on funding for our two proposals for the FY21/FY22 period.  That now looks like it will be further delayed
       until (hopefully) December 18, if Congress passes a budget for FY021 (new starts are forbidden during a Continuing Resolution).  
   Next two weeks (Dec 7 - Dec 18)
     - EIC: I attended meetings, including the Editorial Board.  The upcoming period I will be more involved in editing the CDR.   
     - Isotopes: I prepared two talks for the Isotope Review and dry run some of the others.  The Review went well, with questions on the window. I had contacted ANL to borrow a
       window; they sent the window and the detailed design, which enabled Joe to calculate it. Initially his calculation did not give a positive result. Dave Meekins pointed out that
       it was because Joe was modeling the window as a solid, not a shell.  When it was calculated as a shell, it could be demonstrated to be safe. We finished the week preparing for
       the run. Lila is making progress; I also attended another of the DOE Isotope Program Seminar series - the pet project of our funding manager.    
     - PERLE: there was videoconference where some progress was made.  There is agreement that PERLE can use the AES booster module, and we need to provide a SoW for replacing
       the cavities.  Achille reiterated that he was willing to fund the SRF work at JLab, just needs all of the documents signed!  
     - VNECA: Good meeting to bless the Governors Nuclear Energy Strategic Plan, which we helped develop.  There are opportunities for Jefferson Lab to take an active role, but
       actually, we are on the sidelines.  But it is good for our image in Richmond to be seen to be helping with the Governor’s plans.  
     - Still in Continuing resolution awaiting info on further funding from the DOE Isotope Program.
