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.

He­li­cal Solenoids (HS) were pro­posed for a muon beam ion­iza­tion cool­ing. There are sub­stan­tial up to 30 MeV/m en­er­gy loss­es dur­ing pass­ing the muon beam through an ab­sorber. The main issue of such sys­tem is the en­er­gy re­cov­ery. A con­ven­tion­al RF cav­i­ty has di­am­e­ter which is too large to be placed in­side HS. In the paper pre­sent­ed re­sults of di­elec­tric filled RF cav­i­ty de­sign. The pro­posed cav­i­ty has he­li­cal con­fig­u­ra­tion. Pre­sent­ed He­li­cal Cool­ing Chan­nel mod­ule de­sign which in­cludes: high pres­sure ves­sel, RF cav­i­ty, and su­per­con­duct­ing HS. Dis­cussed pa­ram­e­ters of this mod­ule sub-sys­tems and shown re­sults of muon beam track­ing in com­bined mag­net­ic and elec­tric 3D fields.
