The SSC is a variable energy machine, which was designed to produce protons of maximum beam energy 200 MeV
The magnet system of the SSC comprises four identical C-shape sector magnets. Each of these four sector magnets has a sector angle of 34◦ .
This compromise angle was chosen mainly to avoid serious resonances in the betatron oscillations during acceleration resulting in beam loss.
Each of the sector magnets has three sets of coils, giving it a maximum flux density of 1.265 T in the 66 mm pole gap.
The main field is provided by a single coil layer around the pole tips which provides a flux density of 1.15 T.
Additional coils are wound around the yoke to correct for difference in steel properties between sector magnets.
To preserve isochronism over the radial distance, the flux density must increase by 20% if protons are to be accelerated to 200 MeV. To accomplish this, a set of 29 trim coils is used.
• The RF system of the SSC, consists of two λ/2-resonators with a delta shaped accelerating electrode.
The resonators are each capacitively coupled to a 150 kW power amplifier.
The resonator can be tuned over the resonance frequency range 6 to 26 MHz.
