- 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...

Previous two weeks (Dec 7 - Dec 23)
- 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.

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.
