  Vac­u­um sys­tem for the 3 GeV Tai­wan Pho­ton Source (TPS) has been start­ed the con­struc­tion since 2010. The crit­i­cal com­po­nents such as the bel­lows and gate valves with rf-con­tact shield­ing, pulsed mag­net kick­er ce­ram­ic cham­bers, BPM, crotch ab­sorbers, etc. have been man­u­fac­tured and test­ed. Alu­minum alloy (Al-) vac­u­um cham­bers for the arc-cells have been ma­chined and un­der­go­ing the in-house weld­ing. Mass pro­duc­tion of the vac­u­um equip­ments in­clud­ing the ion gauges, ion pumps, NEG pumps, and gate valves, has been con­tract­ed out and par­tial­ly de­liv­er­ing fol­low­ing the sched­ule of the cell as­sem­bling. Each cell, con­tains two short Al-straight cham­bers and two Al-bend­ing cham­bers, has been start­ed the as­sem­bling and on-site weld­ing on the pre-aligned gird­ers in clean room form­ing an one-piece vac­u­um ves­sel about 14 m in length fol­low­ing by the vac­u­um bak­ing to the ul­tra-high vac­u­um. The con­cep­tu­al de­sign of the vac­u­um sys­tems for the long straight sec­tions, the con­cen­tric boost­er, and the trans­port lines, will be ad­dressed. The progress of pro­to­typ­ing de­vel­op­ment and the sta­tus of con­struc­tion for the TPS vac­u­um sys­tem will be de­scribed in this paper.

  The Tai­wan Pho­ton Source (TPS) is an alu­minum alloy vac­u­um sys­tem with 518.4 m cir­cum­fer­ence di­vid­ed into 24 sec­tions. A6061T6 alu­minum alloy ma­te­ri­al is used for TPS bend­ing cham­bers. Each alu­minum bend­ing cham­ber is com­po­nent of 2 half plates, about 3.5～4.2 m in length and～0.6 m in width, were oil-free CNC ma­chined, ozone cleaned, and TIG weld­ing in clean room. The de­for­ma­tion < 0.1 mm and leak­age rate < 2x10-9m­bar. L/s for each weld­ed bend­ing cham­ber has in­spect­ed and achieved. A bend­ing cham­ber is in­spect­ing the ther­mal out­gassing rate test and ul­ti­mate pres­sure. The man­u­fac­tur­ing and vac­u­um test will be de­scribed in this paper.

  The con­struc­tion of a new 3 GeV syn­chrotron fa­cil­i­ty, Tai­wan Pho­ton Source, is on­go­ing. The vac­u­um sys­tem has been de­signed with off-site bak­ing for arc sec­tion from sec­tor gate valve to sec­tor gate valve. There is no flange used in this arc sec­tion be­sides the two ends con­nect­ed to sec­tor gate valves. It is a te­dious works for in­stall such long vac­u­um sys­tem with alu­minum cham­bers. In this poster, all the de­tailed in­stal­la­tion pro­ce­dures will be de­scribed. All the pre­cau­tion in­spec­tion pro­ce­dures for all vac­u­um com­po­nents to pre­vent failed com­po­nents to be in­stalled will also be de­scribed. Every three weeks, one cell will be as­sem­bled and stored. Ex­pe­ri­ence is being learned and could be used for the vac­u­um sys­tem of fu­ture new ac­cel­er­a­tor like FEL and oth­ers.

  Elec­tro­mag­net­ic in­ter­fer­ence is a crit­i­cal prob­lem for elec­tron­ic equip­ment, es­pe­cial­ly for those so­phis­ti­cat­ed mea­sur­ing sen­sors using in TLS. There­fore, lots of ef­forts have been made to iso­late the EM noise from the kick­er mag­nets. In this ar­ti­cle, dif­fer­ent thick­ness­es of alu­minum cham­bers are ap­plied to block the ra­di­at­ed EM noise. Fur­ther­more, the dif­fer­ent widths of slits sim­u­late the nec­es­sary open­ings on kick­er as­sem­bly. Ac­cord­ing to the re­sults of small-scale ex­per­i­ment, some pa­ram­e­ters are ob­tained to de­sign the en­clo­sure of kick­er mag­net. Com­pared the re­sults with the data from the orig­i­nal scale kick­er, these pa­ram­e­ters pro­vide a be­liev­able guide­line in the be­gin­ning of de­sign sta­tus.

  The pur­pose of this paper is to il­lus­trate the in­stal­la­tion se­quence of TPS SR kick­er. Be­cause of adding the ro­ta­tion func­tion in row di­rec­tion, the po­si­tion of every com­po­nent of kick­er must be very pre­cise. The kick­er mag­net and EMI en­clo­sure were fas­tened on the ro­ta­tion motor plate which could ro­tate ±3.0 mrad. The ce­ram­ic cham­ber re­main fixed on the bot­tom plate in order to let the bel­low stress free dur­ing ro­ta­tion. After in­stal­la­tion, the in­duc­tance mea­sure­ment and the high volt­age break­down test were also test­ed. The ex­per­i­men­tal re­sults showed the good uni­for­mi­ty and reached the ex­pect­ed re­quest. The field map­ping and EMI pre­ven­tion schemes will be test­ed in the fu­ture.
