CYCIAE-100, a 100 MeV high current compact cyclotron has been constructed and first beams were extracted in 2014. The machine has 7 beam lines for multi-application purposes. N1, one of the beam lines, is designed for high current beam transportation, beam dump tests and isotope production. In 2016, a mA proton beam was tested on the internal target. In 2017, 200 micro-ampere proton beam was extracted and transported to the beam dump. This paper will present the simultaneous Dual-beam extraction from CYCIAE-100 and the improvement of the uniformity of the beam on the target.
