Abstract	The usage of high temperature superconductors (HTS) in particle accelerators of higher acceleration energy (in the TeV range) poses certain design concerns that may be conveniently addressed, in the conception phase, through mathematical modeling and numerical simulation. This paper presents the prototype of an YBCO superferric quadrupolar magnet for intense magnetic field of high gradient magnetic field and modeling results on the magnetic field and heat transfer. The temperature of the HTS field winding must be kept within safe limits or the HTS would exit the superconductive state. Therefore cryo-cooling provided by supercooled liquid Nitrogen is used to remove the heat influx from the ambient, which is a menace for the thermal stability of the magnet. First, the magnetic field problem is solved for to assess the degree of uniformity of the magnetic field. Simpler, 2D models provide accurate, useful information on the magnetic field spectra. Next, the heat transfer problem, where radiation plays a major role, is solved. Two-dimensional models may not produce accurate results in this cases. Therefore a 3D geometry abstracted from the CAD design of the prototype was used as computational domain. The numerical simulation results unveil the heat transfer paths within the structure that may be valuable in optimizing the design of the magnet.
