This document outlines the ongoing impedance activities related to the LHC and SPS facilities. Key tasks include work on collimators by team members Hugo and Benoit, new unshielded bellows around ATLAS, and the characterization of various components. The responsibilities are assigned to specific individuals for tasks such as the segmentation of circuits for SPS kickers and RF cavities. Additionally, it discusses the status of various components like beam screens and magnet systems, indicating collaboration and progress on several fronts in accelerator development.
