“…The G4-BIN predictions at the energy of $200 MeV/u agree well with the 950 MeV/u data regardless of the atomic number Z. If the aforementioned experimentally observed energy-independence of the cross section still holds down to 200 MeV/u, we expect a good agreement will be obtained between the data and the G4-BIN predictions at 200 MeV/u, for which the beam energy is being planned for RAON [11][12][13]. In fact, G4-BIN shows a small energy-dependence.…”

“…Their results indicate that TSRS can be indeed effective in producing more exotic medium-mass neutron-rich isotopes. According to the design summary of RAON in Korea [11][12][13], the expected intensity of 132 Sn can be as large as about 10 8 particles per second (pps). It is the unique feature of RAON that the isotopes generated by ISOL can be post-accelerated and injected to the IFF facility for producing more exotic RIBs.…”

a b s t r a c tA so-called ''two-step reaction scheme'', in which neutron-rich rare isotopes obtained from ISOL are post-accelerated and bombarded on a second target, is employed to estimate the production yields of exotic rare isotopes. The production yields of neutron-rich rare isotope fragments induced by 200 MeV/u 132 Sn beams bombarded on a 9 Be target are estimated with Monte Carlo code, GEANT4. To substantiate the use of GEANT4 for this study, benchmark calculations are done for 80 MeV/u 59 Co, 95 MeV/u 72 Zn, 500 MeV/u 92 Mo, and 950 MeV/u 132 Sn beams on the 9 Be target. It is found that 132 Sn beams can produce neutron-rich rare isotopes with 45 6 Z 6 50 more effectively than 238 U beams at the same energy per nucleon.

We have investigated the feasibility of using compound materials as target for muon production by virtue of simulations using a GEANT4 toolkit. A graphite and two thermostable compound materials, beryllium oxide (BeO) and boron carbide (B 4 C) were considered as muon production targets and their muon production rates for 600-MeV proton beam were calculated and compared. For thermal analysis, total heat deposited on the targets by the proton beams and the secondary particles was calculated with a MCNPX code, and then the temperature distribution of target was derived from the calculated heat by using an ANSYS code with consideration for heat transfer mechanisms, such as thermal conduction and thermal radiation. In addition, we have investigated whether the heavy ion beams can be utilized for muon production. For various beam species such as 3 He 2 , 4 He, 7 Li, 10 B and 12 C, their muon production rates were calculated and compared with that obtained for a proton beam.

“…The production target is located at the beginning of this stage (F0). While the stable beam will be provided by the superconducting linear accelerator, SCL1, the RI beam will be provided by the post-accelerator (SCL3) with the ISOL facility [5]. The secondary RI beam will be mainly produced by transfer reaction, but quasi-projectile fragmentation is also phase-space is 5th order and window sizes for (x,a) and (y,b) are 2 cm×200 mrad and 2 cm×400 mrad, respectively.…”

KOBRA (KOrea Broad acceptance Recoil spectrometer and Apparatus) is a mass separator that is being designed for experiments to study nuclear astrophysics, nuclear spectroscopy, symmetry energy and spin polarization with low energy stable/RI beams up to ~20 MeV/nucleon at RAON. KOBRA is divided into two-stage configurations consisting of in-flight separator and recoil spectrometer. The first stage as an in-flight separator consists of double achromatic separator and short length Wien filter. The second stage consists of rotatable QQD-type spectrometer with long length Wien filter. KOBRA has been designed to enable reaction experiments using the RI beams which are produced by not only transfer reactions but also quasi-projectile fragmentation.
