- Continue with the tune space exploration
- Thinking about how to improve the model so as to eliminate the artificial tune dependence of the TCBI growth rate resulted from the over-simplification of the model in our study

Previous two weeks (July 5 - July 16)
- Laser particle counter: Continued data analysis of 6-channel data with 1-2 Hz wire sweeping rate. Vendor visit on July 6 focused on observation of different operating modes and implications on event identification both pre and post data analysis. Currently seeing 3-4 operating modes in which events are often seen in one of the two available signals per channel, and trying to understand why channels switch between operating modes as the system settles. Vendor returned on July 14 with updated software allowing for higher data resolution in both signals (shared bandwidth between the two signals) and an updated algorithm for offline analysis of the signals that relies on calculating and subtracting a noise spectrum from the raw data.
- Discussion with M. Poelker on studies of gas bremsstrahlung in the CEBAF linacs, possibility of detection using radiation monitors, and mitigation efforts including ion clearing gaps. Literature study on gas bremsstrahlung in electron storage rings and ion clearing methods at Cornell. Discussion with M. Poelker and J. Grames on July 12.
Next two weeks (July 19 - July 30)
- Literature study on gas bremsstrahlung in electron storage rings and ion clearing methods. Working with J. Grames and M. Poelker to continue studies of gas bremsstrahlung in the CEBAF linacs.
- Laser particle counter: Continued system debugging, optimization, and data analysis to better understand operational modes. Swapped the sensors driving channels 0 and 2 to test whether the noise in channel 0 is fiber driven or sensor driven. Vendor will return July 27-28 with remaining 18 sensors for full 24 channel capability. The additional sensors should have better signal to noise response than the initial 6 channels.

Previous two weeks (July 5 - July 16)
- Isotopes: a really busy time with several meetings with UVA and NMT. As it stands, UVA will proceed with a proposal that is purely biological, and Jefferson Lab and NMT will not be involved.
- ERL:I gave my ERL talk () on Friday July 9 to about 145 people. This took up a lot of time. The ERL sub-Panel took up even more time as we have wrestled with understanding the CERC. I had the last meeting on the CERC as well as the first meeting where Telnov presented the ERLC. I foresee another frenetic round of interactions between the sub-Panel members who are incredibly active - I regularly have a dozen emails early in the morning as the others get up before me! I contacted Wim Leemans, now at DESY, to try and talk him into participating in PERLE. No follow up from DESY yet. With the loss of Frank Marhauser and all the EIC work, I do not see Jefferson Lab having a big involvement in the SRF for PERLE, so maybe we can work with DESY to participate in the SRF. Hopefully, Alex will be able to continue leading the optics studies.
- HIPERLAC: I responded to questions from Leigh and prepared and delivered a talk (attached).
- ALcC: we had a meeting on July 13 to discuss the ILC status.
Next two weeks (July 5 - July 16)
- Isotopes: a really busy time with several meetings with UVA and NMT. As it stands, UVA will proceed with a proposal that is purely biological, and Jefferson Lab and NMT will not be involved. NMT will lead a proposal to study Scandium47 with irradiations at the Idaho Accelerator Center. We would probably be involved in targeted - still being worked out. The end of project write up for our current isotope funding is due July 30, I haven’t yet started to put it together.
- ERL: I gave my ERL talk File:ERL RD Roadmap July 2021.pdf on Friday July 9 to about 145 people. This took up a lot of time. The ERL sub-Panel took up even more time as we have wrestled with understanding the CERC. Next week, I will have the last meeting on the CERC as well as the first meeting where Telnov will present the ERLC. I foresee another frenetic round of interactions between the sub-Panel members who are incredibly active - I regularly have a dozen emails early in the morning as the others get up before me! I contacted Wim Leemans, now at DESY, to try and talk him into participating in PERLE. We will have a video-conference next week. With the loss of Frank Marhauser and all the EIC work, I do not see Jefferson Lab having a big involvement in the SRF for PERLE, so maybe we can work with DESY to participate in the SRF. Hopefully, Alex will be able to continue leading the optics studies.
- HIPERLAC: I responded to questions from Leigh and next week I have to prepare a talk.
