Abstract
The Rare Isotope Science Project (RISP) was established in December 2011 for the establishment of the accelerator complex (RAON) for the rare isotope science in Korea. The rare isotope accelerator at RAON will provide rare isotope (RI) beams via both the Isotope Separation On-Line (ISOL) and the In-Flight Fragmentation (IF) methods. The energy range of RI beams will be from a few MeV/nucleon to a few hundreds of MeV/nucleon for researches in fields of basic and applied science. Large Acceptance Multi-Purpose Spectrometer (LAMPS) at RAON is a heavy-ion collision experimental facility for studying nuclear symmetry energy by using RI beams. At the end of the IF separator, high energy LAMPS experimental setup (HE-LAMPS) will be located for completing an event reconstruction by detecting all the particles produced in heavy-ion collisions within a large acceptance angle to measure particle spectrum, yield, ratio and collective flow of pions, protons, neutrons, and intermediate fragments at the same time. HE-LAMPS consists of a solenoid spectrometer and a forward neutron wall. A Time Projection Chamber (TPC) and a time-of-flight (ToF) detector will be placed inside of cylindrical solenoid magnet of 0.6 T for charged particle tracking and particle identification. The forward neutron wall will be made of 8 layers of plastic scintillators for neutron tracking. In this presentation, the current status of RAON including the detail physics and design of HE-LAMPS will be discussed.
