In the initial phase, one stable, nearly continuous wave, beam from the ECR ion source and one pulsed radioactive beam from the EBIS charge breeder ion source of the Californium Rare Isotope Beam Upgrade (CARIBU-EBIS) will be interleaved in time via an electrostatic deflector at injection, and accelerated through the first two sections of the linac. At that point, one of the beams is deflected via a fast switching magnet to a lower energy experimental area while the other is further accelerated through the third linac stage of ATLAS. Details of the proposed implementation and the expected gains from this upgrade will be presented. In addition to enhancing the nuclear physics program, this upgrade will allow some applications such as material irradiation, isotope production, and radiobiology [2].
