SPS 200 MHz RF power: some history  The RF-SPS started up in 1976 with two accelerating cavities (technical specs were written in 1971)  For the new role of the SPS as proton-antiproton collider, since 1980, there are four cavities 200 MHz in the SPS May 26, Eric Montesinos / CERN-BE-RF-SR TWC#1 / TX1 TWC#2 / TX TWC#1 / TX1+TX2 TWC#2 / TX3+TX4 TWC#3 / TX5+TX6 TWC#4 / TX7+TX8 RF amplifier 1 mW Coaxial transmission line 125 to 160 meters Accelerating cavity Configuration of one of the four 200 MHz power plant 1 MW 2010

Sections and Cavity One section : 11 drift tubes A cavity is composed of sections of cavity One 4 sections cavity May 26, Eric Montesinos / CERN-BE-RF-SR

Cavities redistribution 2011 : 4 cavities 2 x 4 sections 2 x 5 sections + 3 spare sections 2018 : 6 cavities 2 x 4 sections 4 x 3 sections + 1 spare section May 26, Eric Montesinos / CERN-BE-RF-SR

Cavities re-arrangement May 26, 2011Eric Montesinos / CERN-BE-RF-SR 7  It will be a challenge to re-arrange the whole area  8 cavities in 4 sectors : 6 TWC TWC800  2 x 3 sections cavities fit in a sector  1 x 4 sections cavities + 1 x TWC800  Re-use of the ex-SWC sectors ( ) to re-arrange the pickups (and the dampers ?) Straight section

Cavities re-arrangement  Due to a realignment campaign, we already disassembled all the cavities between 2001 and 2004  We know all the specific needed components, tooling, transport system  We also checked the coaxial lines distribution: difficult, but possible May 26, Eric Montesinos / CERN-BE-RF-SR
