摘要：

There are increasing interests in high temperature superconducting(HTS) undulator with a gradual increase of engineering current density of REBCO conductor. Additionally, no-insulation(NI) winding technique may maximize the undulator field of HTS undulators mainly benefited from its high engineering current density. In this study, we present several design options of an NI HTS undulator to investigate its anticipated performance in terms of magnetic field strength. Specifically, maximum magnetic field along the beam axis depending on the magnetic gap, magnetic period length, winding dimension, and operating temperature is investigated. Then, these results are fitted using a scaling law to easily estimate the anticipated performances of NI HTS undulator at different magnetic gaps and magnetic periods. Finally, a comparison between NI HTS undulator, NbTi based low temperature superconducting undulator, and cryogenic permanent magnet undulator is discussed.
