This paper reports on a proposed design and estimation of performance of a 20 T no-insulation (NI) high temperature superconductor (HTS) standalone user magnet for the National High Magnetic Field Laboratory. It consists of a stack of 18 double pancake coils wound with REBCO tapes from two different...
