  SOLEIL is a third gen­er­a­tion Syn­chrotron ra­di­a­tion source lo­cat­ed in France near Paris. At the mo­ment, the Stor­age Ring de­liv­ers pho­ton beam to 23 beam­lines. Since ma­chine and beam­lines im­prove their per­for­mance, new re­quire­ments are iden­ti­fied. On the ma­chine side, new im­ple­men­ta­tion for feed­for­ward of elec­tro­mag­net­ic un­du­la­tors is re­quired to im­prove beam sta­bil­i­ty. On the beam­lines side, a so­lu­tion is re­quired to syn­chro­nize data ac­qui­si­tion with motor po­si­tion dur­ing con­tin­u­ous scan. In order to pro­vide a sim­ple and mod­u­lar so­lu­tion for these ap­pli­ca­tions re­quir­ing syn­chro­niza­tion, the elec­tron­ic group de­vel­oped a set of elec­tron­ic boards called "SPI board pack­age". In this pack­age, the boards can be con­nect­ed to­geth­er in daisy chain and com­mu­ni­cate to the con­troller through a SPI* Bus. Com­mu­ni­ca­tion with con­trol sys­tem is done via Eth­er­net. At the mo­ment the fol­low­ing boards are de­vel­oped: a con­troller board based on a Cor­tex M3 MCU, 16bits ADC board, 16bits DAC board and a board al­low­ing to pro­cess motor en­coder sig­nals based on a FPGA Spar­tan III. This plat­form al­lows us to embed pro­cess close to the hard­ware with open tools. Thanks to this so­lu­tion we reach the best per­for­mances of syn­chro­niza­tion.

  Time re­solved ex­per­i­ments are one of the major ser­vices that syn­chrotrons can pro­vide to sci­en­tists. The short, high fre­quen­cy and reg­u­lar flash­es of syn­chrotron light are a fan­tas­tic tool to study the evo­lu­tion of phe­nom­e­na over time. To carry out time re­solved ex­per­i­ments, beam­lines need to syn­chro­nize their de­vices with these flash­es of light with a jit­ter short­er than the pulse du­ra­tion. For that pur­pose, Syn­chrotron SOLEIL has de­vel­oped the Tim­BeL board fully in­ter­faced to TANGO frame­work. This paper pre­sents the main fea­tures re­quired by time re­solved ex­per­i­ments and how we achieved our goals with the Tim­BeL board.
