Observation of emittance growth at KEK PS
/ Igarashi, S ; Miura, T ; Nakamura, E ; Shimosaki, Y ; Shirakata, M ; Takayama, K ; Toyama, T
Emittance growth has been observed in the transverse direction at the injection period of the 12 GeV main ring of the KEK proton synchrotron. Measurement of the beam profiles using flying wires has revealed a characteristic temporal change of the beam profile within a few milliseconds after injection. [...]
