Abstract
This paper presents a design concept of an HTS/LTS hybrid dipole with 50 mm
aperture and 20 T nominal field based on a cos-theta coil and a cold iron yoke.
The HTS part of magnet coil uses REBCO Twisted Stacked Tape cable. The LTS part
is graded and made of two Nb3Sn Rutherford cables. Due to high sensitivity of
HTS/LTS coils to large stresses and strains at high fields, a Stress Management
(SM) concept combined with the cos-theta coil geometry is used. The results of
magnet magnetic analysis are presented and discussed.
