Max Bruker
Previous (Dec 7 - Dec 18) - Almost done cleaning up and documenting the IMP data folder. Lots of dusty old stuff to sort through. - Minor remarks on the APS synopsis draft. Next (Dec 21 - Jan 1) - Crucial Conversations class, parts 1 and 2. Mostly common sense, but always a good idea to be reminded of the necessity for continuous self-improvement. - While I still need to finish cleaning up the data folder, the IMP experiment is OVER. We managed to painfully get rid of the errors introduced by the production team, and the article has now been published. It only took little more than a year, counting from the end of the experiment... - Reading the EIC CDR. Haven't gotten very far in terms of making meaningful comments. - UITF beam optics work coming up!

Bhawin Dhital
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 (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.
