Radiation studies for the MOMENT target station
|
摘要
The discovery of the neutrino mixing angle θ_(13) opens new opportunities for the discovery of leptonic CP violation at high intensity neutrino beams.MOMENT,a future neutrino facility with a high-power proton beam of 15 MW from a continuous-wave linac,is focused on that discovery.The high power of the proton beam causes extreme radiation conditions for the facility and especially for the target station,where the pion capture system of five superconducting solenoids is located.In this paper initial studies are performed for the effects of the radiation on the solenoid structure and the area surrounding it.A concept cooling system is also proposed.
