Archisman:
- VSC meeting last week: Current LVK MOU extended to 2026, after LVK will be replaced with IGWN. A part of the discussion has been on IGWN formation, a part has been on the “Lessons learned” document (former “What went wrong”) and a committee has been set up to take care of this document.
- Election of speakers committee: the previous chair stepped down (Eric Chassande-Mottin), and nominations open for the chair role.
- Stable cavities: there has been a very long discussion, but a conclusion has not been reached yet.
- Next VSC meeting conflicts with ET symposium in Maastricht (Tuesday May 7, 2pm), most of us are going: request for replacement at VSC, maybe somebody who is not going to ET
