Development of Rotating Target with Ferrofluid Seal for ILC Electron-Driven Positron Source

In the ILC electron-driven positron source, acceleration tubes are located immediately downstream of the positron generation target to capture the generated positrons, necessitating high vacuum for their operation. We designed a rotating target using a ferrofluid rotating vacuum seal that can stably maintain a vacuum of 10^{-6} Pa and a... Show more
