The high temperature superconducting (HTS) magnet has been made progress in high magnetic field with the second generation (2G) HTS wires in recent years. However, the closed-loop operation of the HTS magnet is rarely to be realized at present due to the immature jointing technique. Based on the high n-value of HTS wires, this paper presents a conceptual design of a superconducting magnet stacked of REBCO annulus plates which is magnetized by flux pump. The effects on trapped field characteristics and temporal stability in the superconducting magnet are analyzed by the finite element method (FEM). The design method of REBCO annulus plates and construction details of superconducting magnets are introduced in this paper. This superconducting magnet is stacked of REBCO annulus plates to realize the closed-loop operation of HTS magnet without jointing and it has significance for the stability application of NMR or MRI magnet.
