Research Abstract

Generation of strong periodic magnetic field in short period is important technology for advanced light sources such as free electron lasers and synchrotron radiation facilities. In this work, a new type of undulator using bulk high-Tc superconductors(HTS) and a solenoid magnet was developed. Undulator field strength of 0. 85 T with period length of 10 mm and gap width of 4 mm was achieved. Through the research, fundamental technology for future undulator was established.
