Abstract :
Computer simulation of the beam loss caused by the charge exchange with a residual gas and a transmission efficiency investigation of the ion optic system have been carried out for the DRIBs transport lines. The DRIBs accelerator complex will include two main ion guide lines for transport of low-energy radioactive ion beams (EI∼15 keV): the line from the RIB-separator of the U400M cyclotron to the U400 cyclotron (‘Phase 1’) and the line from the MT25 microtron to the ECR-source of the U400-cyclotron axial injection system (‘Phase 2’), of the lengths exceeding 120 and 70 m, respectively. The results of the beam-loss numerical simulation and the optimization of the basic parameters of the vacuum and magnet optic systems allow to determine the main requirements for these systems which can provide effective transport of low-energy beams.
