The Fer­n­in­frarot Linac- Und Test-Ex­per­i­ment (FLUTE) is a KIT-op­er­ated linac-based test fa­cil­ity for ac­cel­er­a­tor re­search and de­vel­op­ment as well as a com­pact, ul­tra-broad­band and short-pulse ter­a­hertz (THz) source. As a key com­po­nent of FLUTE, the bunch com­pres­sor (chi­cane) con­sist­ing of four spe­cially de­signed dipoles will be used to com­press the 40-50 MeV elec­tron bunches after the linac down to sin­gle fs bunch length. The max­i­mum ver­ti­cal mag­netic field of the dipoles reach 0.22 T, with an ef­fec­tive length of 200 mm. The good field re­gion is ±40 mm and ±10.5 mm in the hor­i­zon­tal and ver­ti­cal di­rec­tion, re­spec­tively. The lat­est mea­sure­ment re­sults of the dipoles in terms of field ho­mo­gene­ity, ex­ci­ta­tion and field re­pro­ducibil­ity within the good field re­gions will be re­ported, which meet the pre­de­fined spec­i­fi­ca­tions. The mea­sured 3D mag­netic field dis­tri­b­u­tions have been used to per­form beam dy­nam­ics sim­u­la­tions of the bunch com­pres­sor. Ef­fects of the real field prop­er­ties on the beam dy­nam­ics, which are dif­fer­ent from that of the ASTRA built-in di­pole field, will be dis­cussed.
