Beam Dump Fabrication and Simulation by Using PHITS Code and an ANSYS Analysis

초록

The design of a beam dump for the energy range less than 20 MeV is reported. The beam dump was developed for the beam extraction commissioning stage of the Korea Basic Science Institute's( KBSI's) heavy ion facility. At present, the downstream section design of the diagnostic chamber of the beam line was completed, as has the fabrication of a radio-frequency quadrupole(RFQ) section. We are now performing frequency tuning for optimization. For reduction and elimination of the generated beam, the beam dump will be located downstream of the diagnostic beam line, and the beam dump was designed to withstand a heavy-ion beam energy of less than 20 MeV. The PHITS code and ANSYS steady-state thermal analysis were adapted for simulating the heat transfer and determining the numbers and types of secondary particles produced by bombardment of the beam's dump material, respectively.
