 To reach 750 kW, the repetition cycle will be reduced to 1.32 s with 2.0x1014 protons per pulse, while for 1.3 MW the repetition cycle has to be further decreased to 1.16 s and the number of protons per pulse has to increase to 3.2x1014.In addition to increasing the primary proton beam power, the current in the horns focusing secondary particles (pions, kaons, etc.
