For­MAX is an ad­vanced beam­line at MAX IV Lab­o­ra­tory, en­abling multi-scale struc­tural char­ac­ter­i­sa­tion of hi­er­ar­chi­cal ma­te­ri­als from nm to mm length scales with high tem­po­ral res­o­lu­tion. It com­bines full-field mi­cro­to­mog­ra­phy with small- and wide-an­gle x-ray scat­ter­ing (SWAXS) tech­niques, op­er­at­ing at 8-25 keV and pro­vid­ing a vari­able beam size. The beam­line sup­ports SWAXS, scan­ning SWAXS imag­ing, ab­sorp­tion con­trast to­mog­ra­phy, prop­a­ga­tion-based phase con­trast to­mog­ra­phy, and fast to­mog­ra­phy. The ex­per­i­men­tal sta­tion is a ver­sa­tile in-house de­sign, tai­lored for var­i­ous sam­ple en­vi­ron­ments, al­low­ing seam­less in­te­gra­tion of mul­ti­ple tech­niques in the same ex­per­i­ment. The end sta­tion fea­tures a nine-me­ter-long evac­u­ated flight tube with a mo­tor­ized small-an­gle x-ray scat­ter­ing (SAXS) de­tec­tor trol­ley. Ad­di­tion­ally, a gran­ite gantry en­ables in­de­pen­dent move­ment of the to­mog­ra­phy mi­cro­scope and cus­tom-de­signed wide-an­gle x-ray (WAXS) de­tec­tor. These fea­tures fa­cil­i­tate ef­fi­cient switch­ing and se­quen­tial com­bi­na­tion of tech­niques. With com­mis­sion­ing com­pleted in 2022, For­MAX End Sta­tion has demon­strated ex­cel­lent per­for­mance and re­li­a­bil­ity in nu­mer­ous high-qual­ity ex­per­i­ments.

  The APPLE X is a com­pact el­lip­ti­cally po­lar­iz­ing un­du­la­tor with a small round mag­netic gap that pro­vides full po­lar­iza­tion con­trol of syn­chro­tron ra­di­a­tion at a lower cost and in less built-in space than com­pa­ra­ble de­vices. The APPLE X will be the source for MAX IV’s po­ten­tial fu­ture Soft X-ray (SXL) FEL. The me­chan­i­cal de­sign, fi­nite el­e­ment analy­sis op­ti­miza­tion, as­sem­bly process, mag­netic mea­sure­ments, and shim­ming of a full-scale 2 m, 40 mm-pe­riod SmCo per­ma­nent mag­net un­du­la­tor are pre­sented.
