We are now designing a high temperature superconducting (HTS) coil for a skeleton cyclotron, a compact AVF cyclotron applied to mass production of radio-isotopes in medical field. We have developed proto-type HTS compact circular coils using a REBCO wire to test the performance of the HTS coils. The coils were designed as mirror coils of a 10 GHz HTS-ECR ion source with properties of low electric power consumption, low operating cost, high stability and high reliability. The HTS-ECR ion source of 10 GHz will provide doubly charged helium ions for acceleration. This paper presents the current - voltage characteristic of the HTS coils at low temperature in 77K (liquid nitrogen) and 30K. Besides, the magnetic field configuration of the ECR ion source will also be discussed.
