  In this paper, we com­pared the ef­fect of the cy­clotron coil shape on the beam dy­nam­ics. Two mod­els were cre­ated. The first has a con­ven­tional round coil, the sec­ond has a coil that fol­lows the tra­jec­tory of the pro­tons. Pa­ra­me­ters of ex­tracted beams are dis­cussed.

  The first FCC-ee final focus quadru­pole pro­to­type has been de­signed, man­u­fac­tured, as­sem­bled and tested at warm. The pro­to­type is a sin­gle aper­ture quadru­pole mag­net of the CCT type. One edge of the mag­net was de­signed with local mul­ti­pole can­cel­la­tion, whereas the other was left with the con­ven­tional de­sign. An op­ti­mized ro­tat­ing in­duc­tion-coil sen­sor was used. A tech­nique was de­vel­oped to take into ac­count field dis­tor­tions due to the en­vi­ron­ment of the test and dis­tin­guish them from mag­net ef­fects, demon­strat­ing an ex­cel­lent field qual­ity for the pro­to­type.

  The so­le­noids are widely used both in con­ven­tional mag­nets and su­per­con­duct­ing mag­nets in par­ti­cle ac­cel­er­a­tors. The lon­gi­tu­di­nal fields along the lon­gi­tu­di­nal di­rec­tion of the so­le­noids are usu­ally mea­sured with the Hall probe mea­sure­ment sys­tem. How­ever, in some cases, the de­vi­a­tion be­tween the mag­netic cen­ter and me­chan­i­cal cen­ter of the so­le­noid is an­other im­por­tant pa­ra­me­ter and has to be mea­sured ac­cu­rately. In this paper, a de­vice is de­signed and de­vel­oped to mea­sure the cen­ter de­vi­a­tion of the so­le­noid, which can be both used in con­ven­tional mag­nets and su­per­con­duct­ing mag­nets. After the de­vice is fin­ished, some tests are made in the so­le­noid to check whether the data is cor­rect. For the nu­mer­i­cal sim­u­la­tion and analy­sis of the mag­netic field in­side the so­le­noid, the TOSCA code was cho­sen right from start. The re­sults of the analy­sis are com­pared to the re­sult of the tests.
