The new SC-ECRIS consists of fully SC magnets and is designed to produce the beams of more than a hundred µA. RILAC is also currently being upgraded by adding superconducting (SC) rf cavities. The beam losses not only in the cavities but also in the beam pipes neighboring them must be avoided to keep the environment in the cold section as clean as possible. Thus, the high-intensity beam with well-controlled emittance is required for this SHE project. To meet the requirement, we use a triplet slits to limit the transverse emittance of the beam in the low energy beam transport (LEBT). In this contribution, we report the recent developments and the property of the first beam extracted from the new 28-GHz SC-ECRIS.
