Syn­chro­tron ra­di­a­tion beam­lines trans­port X-rays from the elec­tron beam source to the ex­per­i­men­tal sam­ple. Pre­cise align­ment of the beam­line op­tics is re­quired to achieve ad­e­quate beam prop­er­ties at the sam­ple. This process is often done man­u­ally and can be quite time con­sum­ing. Fur­ther, we would like to know the prop­er­ties at the sam­ple in order to pro­vide meta­data for X-ray ex­per­i­ments. Di­ag­nos­tics may pro­vide some of this in­for­ma­tion but im­por­tant prop­er­ties may re­main un­mea­sured. In order to solve both of these prob­lems, we are de­vel­op­ing tools to cre­ate fast on­line mod­els (also known as dig­i­tal twins). For this pur­pose, we are cre­at­ing re­duced mod­els that fit into a hi­er­ar­chy of X-ray mod­els of vary­ing de­grees of com­plex­ity and run­time. These are im­ple­mented within a soft­ware frame­work called Sirepo-Bluesky* that al­lows for the com­pu­ta­tion of the model from within a Bluesky ses­sion which may con­trol a real beam­line. This work is done in col­lab­o­ra­tion with NSLS-II. We pre­sent the sta­tus of the soft­ware de­vel­op­ment and beam­line mea­sure­ments in­clud­ing re­sults from the TES beam­line. Fi­nally, we pre­sent an out­look for con­tin­u­ing this work and ap­ply­ing it to more beam­lines at NSLS-II and other syn­chro­tron fa­cil­i­ties around the world.
