The IFMIF-EVE­DA ac­cel­er­a­tor will be a 9 MeV, 125 mA CW deuteron ac­cel­er­a­tor which aims to val­i­date the tech­nol­o­gy that will be used in the fu­ture IFMIF ac­cel­er­a­tor. The SRF Linac de­sign is based on su­per­con­duct­ing Half Wave Res­onators (HWR) cav­i­ties op­er­at­ing at 4.4 K. Due to space charge as­so­ci­at­ed to the high in­ten­si­ty beam, a short, but strong, su­per­con­duct­ing fo­cus­ing mag­net pack­age is nec­es­sary be­tween cav­i­ties. The se­lect­ed con­fig­u­ra­tion has been a su­per­con­duct­ing NbTi solenoid act­ing as a mag­net­ic lens and a con­cen­tric outer solenoid in an­tipar­al­lel con­fig­u­ra­tion to re­duce the dan­ger­ous stray field on the cav­i­ties. The se­lect­ed ar­range­ment for the steer­ers is a pair of par­al­lel race­track coils for each ver­ti­cal and hor­i­zon­tal axis. This paper de­scribes the man­u­fac­tur­ing tech­niques of the dif­fer­ent coils, and the test re­al­ized in warm and cold con­di­tions, with spe­cial at­ten­tion to the train­ing test of the main solenoid, as the nom­i­nal work­ing point in the load line is very high (86.2%).
