Homework #1 About APS upgrade commissioning at APS APS is now in the beam lines commissioning phase see https://www.aps.anl.gov/APS-Upgrade Swap-out injection was successfully tested last April: https://www.aps.anl.gov/APS-News/2024-04-30/worlds-first- successful-multi-bunch-swap-out-injection-demonstrated-at-the So apparently, there are interesting new results to be presented in abstract 993

Homework #2 About abstract 1660 Monika Yadav is a post-doc at UCLA. Started to publish in 2020 => early career scientist. (Source: https://scholar.google.com/citations?user=8TmWFDMAAAAJ&hl=en ) Her abstract is close to a recently published preprint on ArXiV: https://arxiv.org/abs/2409.00186 Interesting comparison of radiation in ion channelling and undulator in a regime where a discrepancy was previously observed.

Homework #3 Consider abstract #875 (Korea talk) in round 2. 1st vote: 1 2ndvote: 2 Score=4 Yes, this talk is suited for MC2 and has a comparable score to other contributed orals. Need to replace another Asia talk. 2 Chinese talks, among them on one quantum materials (timey). Suggest to replace #873 Physics design progress of the HALF project.
