In this re­port the de­vel­op­ment of a quadrupole mover with sub­mi­cron re­peata­bil­i­ty is re­port­ed, which will be used in the in­ter­sec­tions of the Un­du­la­tor Sys­tems of the Eu­ro­pean XFEL (EXFEL). It is part of the Span­ish in-kind con­tri­bu­tion to this fa­cil­i­ty. The main spec­i­fi­ca­tions in­clude sub­mi­cron re­peata­bil­i­ty for a 70 kg quadrupole mag­net with­in com­pact di­men­sions and a ±1.5 mm stroke in the ver­ti­cal and hor­i­zon­tal di­rec­tion. Com­pact lin­ear ac­tu­a­tors based on 5-phase step­ping mo­tors have been cho­sen. Ver­ti­cal ac­tu­a­tor works in a wedge con­fig­u­ra­tion to take me­chan­i­cal ad­van­tage. A closed-loop con­trol sys­tem has been de­vel­oped to achieve this re­peata­bil­i­ty. For the feed­back, one LVDT sen­sor for each axis was used. Me­chan­i­cal switch­es are used to limit move­ment. In ad­di­tion, hard-stops are in­clud­ed for emer­gen­cy. Pro­to­typ­ing stage is done and a se­ri­al pro­duc­tion of more than 90 de­vices is ex­pect­ed, so in­tense work has been done to achieve a re­li­able in­dus­tri­al pro­duc­tion and val­i­da­tion. In this re­port, re­sults of me­chan­i­cal mea­sure­ments in­clud­ing re­pro­ducibil­i­ty, tests of dif­fer­ent op­er­a­tion strate­gies and crit­i­cal sit­u­a­tions will be re­port­ed.

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%).

The Eu­ro­pean X-ray Free Elec­tron Laser (EXFEL) will be based on a 10 to 17.5 GeV elec­tron linac. Its beam will be used in three un­du­la­tor sys­tems to ob­tain ul­tra-bril­liant X-ray flash­es from 0.1 to 6 nanome­tres for ex­per­i­men­ta­tion. The un­du­la­tor sys­tems are formed by 5m long un­du­la­tor seg­ments and 1.1m long in­ter­sec­tions in be­tween. They ac­com­mo­date a quadrupole on top of a pre­ci­sion mover, a beam po­si­tion mon­i­tor, two air coil cor­rec­tors and a phase shifter. The func­tion of the phase shifter is to ad­just the phase of the elec­tron beam with re­spect to that of the ra­di­a­tion field when the wave­length is changed by tun­ing the gap. In this con­text, CIEMAT will de­liv­er 92 phase shifters, as part of the Span­ish in-kind con­tri­bu­tion to the EXFEL pro­ject. This paper de­scribes the en­gi­neer­ing de­sign, the man­u­fac­tur­ing tech­niques and the me­chan­i­cal and mag­net­ic tests re­al­ized on the first pro­to­types.
