1. SPS point 3 New RF building LIU-SPS-200 MHz Power Upgrade April 19, 2011Eric Montesinos / CERN-BE-RF-SR

2. 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 operating @ 200 MHz in the SPS April 19, 2011 2 Eric Montesinos / CERN-BE-RF-SR 20102000 1976 TWC#1 / TX1 TWC#2 / TX2 19901980 1975 1978 TWC#3 / TX3 1979 TWC#4 / TX4 1980 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 Terminating loads Configuration of one of the four 200 MHz power plant 1 MW

5. 2011 amplifiers Two ‘Siemens’ Amplifiers (2 x 1MW RF ~ 450 m2 + 100 m2) Two ‘Philips’ amplifiers (2 x 1 MW RF ~ 500 m2 + 200 m2) April 19, 2011 5 Eric Montesinos / CERN-BE-RF-SR

6. 2018 : Proposed two new power amplifiers  Two new power amplifiers will be build : 2 x 1.7 MW peak RF  Efficiency ~ 50 % -> 2 x 3.4 MVA ~ 7 MVA peak April 19, 2011 6 Eric Montesinos / CERN-BE-RF-SR One line (input cavity ~120 to 180 m away) Drivers: 16 SSA 8 kW From Beam Control Final 16 Tubes 110 kW (g = 12 dB) 3 dB combiners and power loads plus 120 to 180 m Coaxial lines - 0.6 dB - 0.2 dB = - 0.8 dB Tetrodes = 1.4 MW + 0.8 dB = 1.7 MW / 16 = 110 kW 1/16 splitter

7. 2018 : Proposed two new power amplifiers  Could be :  2 x 1.7 MW Klystron  2 x 4 x 450 kW Diacrodes  2 x 8 x 225 kW IOTs  2 x 8 x 225 kW tetrodes  Equivalent to ‘Siemens’  ~ 500 m2 + 200 m2  2 x 16 x 110 kW Tetrodes  Equivalent to ‘Philips’  ~ 500 m2 + 200 m2  2 x 1800 x 1 kW SSA  Equivalent to 10 x SOLEIL  ~ 500 m2 + 200 m2 SOLEIL amplifiers April 19, 2011 7 Eric Montesinos / CERN-BE-RF-SR
