Three families of superconducting cavities accelerate the beam to its final energy of 2 GeV, firstly a section using double-spoke cavities up to an energy of ~216 Mev, then two families of elliptical cavities which are optimized for medium and high energy proton acceleration at a frequency of 704.42 MHz.
Three families of superconducting cavities are used to accelerate the beam to its final energy of 2 GeV. Initially, a section utilizing double-spoke cavities boosts the energy to around 216 Mev, followed by two families of elliptical cavities optimized for proton acceleration at medium and high energies at a frequency of 704.42 MHz.
