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

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
