• Gas-jet type ISOL
• Target design
• Optimization simulation
• U-235 target
• Al degrader

In order to increase the amount of U-235 in the target chamber for KUR-ISOL, the thicknesses of the U-235 target and its protective Al covering were reexamined and optimized by calculating the ranges of typical fission products in the target chamber with a SRIM code. It was found that the U-235 target could be thickened by up to 6 times of the present target for heavy fission products. Our future plan of relocating the target chamber to another irradiation port at KUR is also described.
