Current impedance activities • LHC DS collimators Hugo • New unshielded bellows around ATLAS Olav • SPS pumping ports (shielded, unshielded) Olav • SPS enamel flanges Benoit • Clearing electrode to be assigned (probably Benoit) • PS wirescanners Benoit (sim), Hugo and Olav (meas) • Segmentation, internal and external circuits of SPS kickers Carlo • Serigraphy for SPS kickers Carlo and Hugo • Material characterization Carlo • Finite length Nicolo • Flat, elliptic chambers Nicolas
In "sleep mode” • LHC: • MKI and MKD: worked on by Hugo • collimators with BPMs: worked on by Hugo • PIMS: worked on by Benoit and Olav. • RF cavities: to be assigned • Rotatable Collimators : to be worked on by Hugo • beam screen weld: worked on by Nicolas and Carlo • beam screen holes: to be assigned • TDI: to be assigned • Septa: to be assigned • Trapped modes in collimators: worked on by Hugo • SPS: • MSE, MST and ZS: worked on by Benoit • kicker transitions: worked on by Hugo • laminated steel kicker worked on by Carlo and Benoit • PS: • Extraction kickerrequest by Sandra Aumon on February 2011: to be assigned • PSB: • Y piece and ceramic chamber (M. Barnes and W. Wetterings): to be assigned
