  The Grad­u­ate Uni­ver­sity for Ad­vanced Stud­ies, known as SO­K­ENDAI, pro­vides ed­u­ca­tional op­por­tu­ni­ties for grad­u­ate stu­dents in col­lab­o­ra­tion with na­tional re­search in­sti­tu­tions in Japan. KEK is one of the in­sti­tutes, and has a pro­gram "Ac­cel­er­a­tor Sci­ence". Since 2019, we started two classes: lec­tures "In­tro­duc­tion to ac­cel­er­a­tor con­trol sys­tem" for one se­mes­ter, and a two-day sem­i­nar "Con­trol of dis­trib­uted de­vices for large sys­tems". The for­mer con­sists of 12 lec­tures on var­i­ous top­ics of ac­cel­er­a­tor con­trols by teach­ers, fol­lowed by a pre­sen­ta­tion day by stu­dents. The lat­ter con­sists of lec­ture and hands-on, which en­ables stu­dents to prac­tice EPICS with Rasp­berry-pi based de­vices. In the paper, sta­tus of ac­cel­er­a­tor con­trol classes are re­ported.

  The elec­tron and positron ac­cel­er­a­tor com­plex at KEK of­fers unique ex­per­i­men­tal op­por­tu­ni­ties in the fields of el­e­men­tary par­ti­cle physics with Su­perKEKB col­lider and pho­ton sci­ence with two light sources. In order to max­i­mize the ex­per­i­men­tal per­for­mances at those fa­cil­i­ties the in­jec­tor LINAC em­ploys pulse-to-pulse mod­u­la­tion at 50 Hz, in­ject­ing beams with di­verse prop­er­ties. The event-based con­trol sys­tem ef­fec­tively man­ages dif­fer­ent beam con­fig­u­ra­tions. This in­jec­tion scheme was ini­tially de­signed 15 years ago and has been in full op­er­a­tion since 2019. Over the years, quite a few en­hance­ments have been im­ple­mented. As the event-based con­trols are tightly cou­pled with mi­crowave sys­tems, ma­chine pro­tec­tion sys­tems and so on, their mod­i­fi­ca­tions re­quire metic­u­lous plan­ning. How­ever, the di­verse re­quire­ments from par­ti­cle physics and pho­ton sci­ence, stem­ming from the dis­tinct na­ture of those ex­per­i­ments, often ne­ces­si­tate pa­tient ne­go­ti­a­tion to meet the de­mands of both fields. This pre­sen­ta­tion dis­cusses those op­er­a­tional as­pects of the mul­ti­dis­ci­pli­nary fa­cil­ity.
