초록
A solid-state lithium (Li) target for 2.5 MeV, 20 mA proton beam (PB) accelerator boron neutron capture therapy (BNCT) was developed at the Energy Research Institute of Hefei National Comprehensive Science Center (Anhui Energy Laboratory). The Li target must withstand a high heat flux (HHF) of up to 2.8 MV/m2 generated by the PB bombardment. The research team designed an optimized cross-rib structure. To test the thermal removal ability of the structure, electron beam thermal loading experiments verified its effective performance. The results showed that the designed Li target meets the requirement to remove the thermal load generated by the PB (2.8 MW/m2).
