Strip­per foil is a key equip­ment for con­vert­ing neg­a­tive hy­dro­gen ions into pro­tons in the RCS in­jec­tion zone of CSNS. The struc­ture of the CSNS pri­mary strip­per foil adopts a ro­tat­ing steel strip struc­ture, and the re­place­ment time of the foil is long, re­quir­ing op­er­a­tors to carry out main­te­nance work in close prox­im­ity for a long time. The en­ergy of CSNS-II in­jec­tion beam has sig­nif­i­cantly in­creased from 80MeV to 300MeV, and the ra­di­a­tion dose in the in­jec­tion area will also in­crease, mak­ing it im­pos­si­ble to main­tain the equip­ment in close prox­im­ity for a long time. There­fore, it is nec­es­sary to re­design the pri­mary strip­per foil. This ar­ti­cle will an­a­lyze the strip­per ef­fi­ciency and beam in­jec­tion ther­mo­dy­nam­ics of CSNS-II strip­per foil, carry out au­to­matic foil store re­place­ment struc­ture de­sign, mo­tion analy­sis, and pro­to­type test­ing, and en­vi­sion re­mote main­te­nance so­lu­tions to achieve main­te­nance and re­pair of the strip­per foil with min­i­mal human in­ter­ven­tion.

The pri­mary strip­per foil de­vice is one of the most crit­i­cal de­vices of The China Spal­la­tion Neu­tron Source Pro­ject Phase-II (CSNS-II), which re­quires reg­u­lar foil re­place­ment main­te­nance to en­sure its sta­ble op­er­a­tion. To mit­i­gate the po­ten­tial haz­ards posed to work­ers by pro­longed ex­po­sure to high lev­els of ra­di­a­tion, a main­te­nance ro­botic sys­tem has been de­vel­oped to per­form repet­i­tive and pre­cise foil chang­ing task. The pro­posed frame­work en­com­passes var­i­ous as­pects of the ro­botic sys­tem, in­clud­ing hard­ware struc­ture, tar­get de­tec­tion, ma­nip­u­la­tor kine­mat­ics de­sign, and sys­tem con­struc­tion. The cor­rect­ness and ef­fi­ciency of the sys-tem are demon­strated through sim­u­la­tions car­ried out using ROS Moveit! and GAZEBO.

  This paper de­vel­oped a ded­i­cated dis­as­sem­bly and as­sem­bly hand­cart for CSNS mag­netic alloy cav­ity vac­uum cham­ber. The op­ti­mal sup­port­ing sec­tion struc­ture was de­ter­mined by the use of ANSYS to an­a­lyze the strength of dif­fer­ent sec­tions. The stress sit­u­a­tion of the hand­cart was im­proved by adding an ex­ten­sion rod at the end of the hand­cart. The in­stal­la­tion po­si­tion of the hand­cart was de­ter­mined by the cen­ter po­si­tion of the as­so­ci­ated equip­ment. The de­vel­op­ment of the dis­as­sem­bly and as­sem­bly hand­cart struc­ture was com­pleted through struc­tural op­ti­miza­tion, dis­as­sem­bly and as­sem­bly process analy­sis, and po­si­tion­ing scheme de­sign. The de­vel­op­ment of a hand­cart can im­prove the po­si­tion­ing ac­cu­racy of the vac­uum cham­ber and pre­vent dam­age to the vac­uum cham­ber dur­ing dis­as­sem­bly and as­sem­bly process.
