  For car­ry­ing out bead-pull char­ac­ter­i­sa­tion of RFQ and DTL at the Low En­ergy High In­ten­sity Pro­ton Ac­cel­er­a­tor of BARC, a con­troller for si­mul­ta­ne­ous mo­tion of 64 axis, tuners or post cou­plers, was de­vel­oped. Also, a bead mo­tion con­troller with in­te­grated phase mea­sure­ment sen­sor was de­vel­oped. The paper dis­cusses the re­quire­ments of the sys­tem, the ar­chi­tec­ture of the con­trol sys­tems, op­er­a­tion and re­sults. The re­sults ob­tained from the sen­sor was com­pared to that ob­tained using an in­de­pen­dent USB VNA. The ad­van­tages of the sys­tem es­pe­cially with ad­di­tion of in­ter­nal phase mea­sure­ment sen­sor in­clud­ing min­imis­ing po­si­tion error, flex­i­bil­ity in bead­pull to se­lec­tively in­crease res­o­lu­tion at spec­i­fied lo­ca­tions and ease of im­ple­ment­ing auto-tun­ing al­go­rithms are dis­cussed.
