Layout of the In-flight Fragment Separator Local shielding & remote handling in pre- separator area

A current configuration of the fragment separator and the beam delivery line Separator Configuration 1. Pre-separator S-shape, 4 dipoles 2. Main-separator C-shape, 4 dipoles

IF 분리장치 주요 부분품 개발계획 1. High-power target - high-power e-beam tests underway - design of multi-layer target (ANSYS) - considering multi-layer target at BIPP in Rissia 2. In-flight fragment separator magnets - conventional (or superferric) dipole magnet - superconducting superferric quadrupole magnet - HTC coil dipole and quadrupole magnet (warm iron) 3. Beam dump - thermo-mechanical analysis and mechanical design - considering water cooling loop design 4. Beam measurement devices - attending beam tuning of BigRIPS at RIKEN - development of some detectors underway
