In "sleep mode” LHC: SPS: PS: PSB: 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 kicker request by Sandra Aumon on February 2011: to be assigned PSB: Y piece and ceramic chamber (M. Barnes and W. Wetterings): to be assigned
