Mar, Christoph, Richard Thanks for the draft document. I will not be able to attend on Thursday (Dutch Queen's birthday, I expect they execute you if you don't celebrate correctly). I have some comments and a question: 1) It would be useful to sketch in the filters in the drawing (and are people working on new ones?) 2) It would be useful to label the zone for preparing detectors in the drawing and question: how much time do CMS use per year, and how many periods, in this mode where there is a beam-pipe through the zone?
