Lin­ear ac­cel­er­a­tors based on a su­per­con­duct­ing tech­nol­o­gy need var­i­ous su­per­con­duct­ing mag­nets in­stalled in­side SCRF Cry­omod­ules. At front end of Lin­ear Ac­cel­er­a­tors in­stalled rel­a­tive­ly weak iron-dom­i­nat­ed mag­nets. The fo­cus­ing quadrupoles have in­te­grat­ed gra­di­ents in the range of 1 T - 4 T, and aper­tures 35 mm - 90 mm. At Fer­mi­lab were de­signed su­per­con­duct­ing dipole cor­rec­tors, and quadrupoles for var­i­ous pro­jects. In the paper pre­sent­ed these mag­net de­signs, and test re­sults of fab­ri­cat­ed dipole cor­rec­tor. There are also briefly dis­cussed: mag­net­ic and me­chan­i­cal de­signs, quench pro­tec­tion, cool­ing, fab­ri­ca­tion, and as­sem­bly in­side cry­omod­ule.

In an at­tempt at demon­strat­ing an av­er­age field gra­di­ent of 31.5 MV/m as per the de­sign ac­cel­er­at­ing gra­di­ent for ILC, a pro­gram called S1-Glob­al is in progress as an in­ter­na­tion­al re­search col­lab­o­ra­tion among KEK, INFN, FNAL, DESY and SLAC. The S1-Glob­al cry­omod­ule will con­tain eight su­per­con­duct­ing cav­i­ties from FNAL, DESY and KEK. The cry­omod­ule will be con­struct­ed by join­ing two half-size cry­omod­ules, each 6 m in length. The mod­ule con­tain­ing four cav­i­ties from FNAL and DESY has been con­struct­ed by INFN. The mod­ule for four KEK cav­i­ties is being mod­i­fied at pre­sent. The as­sem­bly of the cry­omod­ules is sched­uled from Jan­uary 2010, and the op­er­a­tion of the sys­tem is sched­uled from June 2010 at the KEK-STF. In this paper, the con­struc­tion of the S1-Glob­al cry­omod­ule will be pre­sent­ed.
