| 1. A method of manufacturing a high temperature superconducting (HTS) tape coil for an MRI device with enhanced protection,
the method comprising:
providing an HTS tape having an electrically conductive silver or silver alloy sheathing on an outer and inner side thereof;
attaching a high-Q capacitor at each end of an HTS tape;
removing using an etching solution of aqueous ammonium hydroxide and hydrogen peroxide substantially all of the silver or
silver alloy electrically conductive sheathing on an inner side of the HTS tape while retaining substantially all of the electrically
conductive silver or silver alloy sheathing material on the outer side of the HTS tape.
