  Under RISP project, wide variety of intense rare isotope ion beams will be provided. An EBIS charge breeder has been designed to charge breed these beams. Its optimum operation requires injection of bunched beam with high quality. An RFQ cooler buncher RFQCB is designed to meet these requirements. To meet the EBIS beam requirements, RFQCB should efficiently accept high intensity continuous beams and deliver to the EBIS bunched beams with small emittance (3 '.mm.mrad), low energy spread (< 10 eV) and short bunch width (2-10 μs). A new design concept to be implemented in this RFQCB have been developed, including a novel injection/extraction electrodes geometry, new RF voltages with frequency up to 10 MHz and amplitude up to 10 kV with improved differential pumping system. Simulations have shown the efficient handling of beam intensities which were never handled so far with improved beam quality. An overview of the RFQCB design concept will be presented. Simulated performance of the device and design of different sub-systems will be discussed. Beam parameters will be measured using Faraday cups and emittance meter. The design of these diagnostics tools will be described as well.
