In April 2023, a new 5-years budget for several time-critical workpackages in ILC was approved.As for the electron driven positron source, complete set of prototype, including rotating target, flux concentrator, solenoid and accelerating structure, will be built in KEK within a few years. Since basic structure of the new source is similar to the one used in the SuperKEKB, we use and integrate previous operation manufacturing and design experiences as much as possible to accelerate new design. Detail design and simulation of each component are ongoing now and the latest results will be presented in the talk.
