μRWELL-PICOSEC: Precision Timing with Resistive Micro-Well Detector
/ Gnanvo, K. (Jefferson Lab) ; Aleksan, R. (IRFU, Saclay) ; Angelis, Y. (Aristotle U., Thessaloniki ; Thessaloniki U.) ; Aune, S. (IRFU, Saclay) ; Bortfeldt, J. (LMU Munich (main)) ; Brunbauer, F. (CERN) ; Brunoldi, M. (Pavia U. ; INFN, Pavia) ; Chatzianagnostou, E. (Aristotle U., Thessaloniki ; Thessaloniki U.) ; Datta, J. (SUNY, Stony Brook) ; Dehmelt, K. (Jefferson Lab) et al.
The PICOSEC detector concept uses a micro-pattern gaseous detector (MPGD) amplification structure combined with a Cerenkov radiator coated with a semi-transparent photocathode to provide below tens of picosecond-level precision timing capabilities with minimum ionizing particles. [...]

First comments on a descoped/staged FCC-ee
/ Blondel, Alain (LPNHE, Paris) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Janot, Patrick (CERN) ; Wilkinson, Guy (Oxford U.)
In response to its remit, the European Strategy Group (ESG) recommended the electron-positron Future Circular Collider (FCC-ee) as the preferred option for the next flagship collider at CERN; and a descoped FCC-ee as the preferred alternative option (with reduced synchrotron radiation (SR) power, without a run at the $\rm t \bar t$ threshold, and with only two interaction regions) in the event that the preferred option turns out not to be feasible.
