Rare isotope Accelerator complex for ON-line experiments (RAON), which is being constructed in Korea, will provide both rare isotope and stable ion beams for various nuclear physics experiments as well as other applications, at a wide energy range up to a few hundreds of MeV/nucleon. The ion beams will be provided to low-energy experimental facilities at RAON such as Korea Broad Acceptance Recoil spectrometer and Apparatus (KoBRA) and Nuclear Data Production System (NDPS). Since the bunch length of some ion beams becomes unsuitably long at the targets of these facilities, a re-bunching system has been designed and developed. Besides, a pre-bunching system based on a fast chopper and a Double Gap Buncher (DGB) has been developed and installed upstream of the Radio-Frequency Quadrupole (RFQ) to lower the repetition rate for the time-of-flight measurements of secondary particles at KoBRA and NDPS. We present the status of the pre-bunching and re-bunching systems for the RAON low-energy experimental facilities. [ABSTRACT FROM AUTHOR]

The ISAC post accelerator comprises an RFQ, DTL and SC-linac. The high energy beam lines connect the linear accelerators as well as deliver the accelerated beams to two different experimental areas. The medium energy beam transport (MEBT) line connects the RFQ to the DTL. The high energy beam transport (HEBT) line connects the DTL to the ISAC-I experimental stations (DRAGON, TUDA-I, GPS). The DTL to superconducting beam (DSB) transport line connects the ISAC-I and ISAC-II linacs. The superconducting energy beam transport (SEBT) line connects the SC linac to the ISAC-II experimental station (TUDA-II, HERACLES, TIGRESS, EMMA and GPS). All these lines have the function of transporting and matching the beams to the downstream sections by manipulating the transverse and longitudinal phase space. They also contain diagnostic devices to measure the beam properties. [ABSTRACT FROM AUTHOR]
