The high-power production target system of the superconducting RI beam separator
BigRIPS [1,2,3] at RI beam factory (RIBF) was constructed in 2007 and has been
successfully operated since then with the beam powers up to 8 kW. The system
was designed to withstand the energy loss of 22 kW in a Be target of 5.4mm
(1g/cm$^{2}$) thickness for a $^{238}$U beam at 345 MeV/nucleon and 1...

Thermal model simulations using the finite element analysis code ANSYS have
been performed for the high power production target system [1,2,3] of BigRIPS
separator at RI beam factory (RIBF). In order to evaluate the cooling capacity
of the target system, the model simulation is particularly important since
available beam power of the RIBF is limited about 1/8 of the goal beam power of...

During some experiments at GANIL, it was observed that some targets were soon deteriorated at very low intensity of heavy ion beam while the estimated temperature at equilibrium was far below the melting point of the material. An explanation of this observation would be the induced tracks due to irradiation of targets with heavy ion beams which result from the quench of the liquid phase of the...

Metallic foils are often employed as windows for gas and liquid targets. They are also used to isolate the beamline vacuum from target materials at accelerator facilities. These beam exit windows normally consist of two closely spaced foils through which a high flow-rate gas is circulated to remove the heat induced by the beam. Helium-cooled Havar windows are popular in radionuclide production...
