PROJECT OF HIGH POWER STATIONARY NEUTRON TARGET OF CONICAL SHAPE

Presented is the proposal for the high intensity neutron target with the converter made of beryllium. The target comprises the stationary conical shape converter cooled by liquid. It is irradiated by the proton beam with energy 10 MeV and average power up to 300 kW. The target cooling is discussed for both water and liquid metal carriers. It is shown that in the case of water cooling the optimum target design is determined by the cooling channel wall temperature - it must not exceed water boiling temperature; in the case of liquid heat carrier target parameters are determined by the thermo- mechanical stress in it. Also problems of target design and materials selection are considered.
