  The Tai­wan Pho­ton Source (TPS) is a 3-GeV third-gen­er­a­tion source of syn­chrotron ra­di­a­tion with beam cur­rent 500 mA stored in the stor­age ring. A front end al­lows in­tense syn­chrotron light gen­er­at­ed in the stor­age ring to pass through to a beam­line. Most heat load of the syn­chrotron light is re­moved in the front ends to pro­tect the beam­line com­po­nents. Align­ment of front-end com­po­nents be­comes im­por­tant to pre­vent dam­age from the large heat load. Be­cause of the many front ends and the brief pe­ri­od of in­stal­la­tion, the align­ment work should be easy, quick and re­li­able. Using a shim method, the ad­justable de­grees of free­dom are de­creased from six to two. This ad­just­ment work be­comes eas­i­er and quick­er. The align­ment of a front-end pro­to­type is de­scribed here.

  In this paper, the sur­vey sta­tus at NSRRC site duirng the TPS (Tai­wan Pho­ton Source) civil con­struc­tion is de­scribed. The TLS (Tai­wan Light Source) ring is still under op­er­a­tion in the mean­time. In order to main­tain the TLS for nor­mal op­er­a­tion and also mon­i­tor­ing the build­ing con­struc­tion, an ex­pand­ed sur­vey se­tups in­clud­ing per­ma­nent lev­el­ing and GPS mon­u­ments were in­stalled both on the site and TPS build­ing. Com­bined with the orig­nal TLS sur­vey sock­ets and sen­sor mon­i­tor­ing sys­tem (hy­dro­stat­ic lev­el­ing sys­tem and pre­ci­sion in­cli­na­tion sen­sors) in­stalled both in the TLS stor­age ring and beam­lines, an ex­ten­sive sur­vey tasks were per­formed. The ground de­for­ma­tion sit­u­a­tion of the TLS and de­vi­a­tion of the TPS build­ing con­struc­tion are pre­sent­ed.

  A novel op­ti­cal in­spec­tion ar­chi­tec­ture is de­signed and de­vel­oped for po­si­tion­ing the TPS (Tai­wan Pho­ton Source) quadrupole and sex­tupole mag­nets on the gird­er with­in 30 um. This po­si­tion­ing sys­tem is a laser-based scheme con­sists of two laser po­si­tion sens­ing de­vices (PSD) and two gran­ite blocks as the stan­dard ref­er­ence of mag­nets. The laser po­si­tion sens­ing de­vice (PSD) is mount­ed on an ad­justable cir­cu­lar steel mod­ule and the mod­ule is in­stalled in a gran­ite block. With the PSD po­si­tion being ad­just­ed and cor­rect­ed, the PSD mod­ule cen­ter can be iden­ti­cal to the ideal pole po­si­tion of mag­nets on the gird­er with­in 10um. The Laser ray is also ad­just­ed and aligned ac­cord­ing to the ideal ref­er­ence line of mag­nets. Fi­nal­ly the gran­ite blocks are re­placed with the quadrupole and sex­tupole mag­nets at in­stal­la­tion, the as­sem­bling error of mag­nets can be de­tect­ed from the PSD mod­ule. This paper de­scribes the de­tail of the sys­tem de­vel­op­ment and test­ing re­sults.

  The TPS (Tai­wan Pho­ton Source) pro­ject is now under civil con­struc­tion. The whole build­ing is con­struct­ed half un­der­ground and 12m deep com­pared to the TLS due to the sta­bil­i­ty con­sid­er­a­tion, so the sur­vey and align­ment works are quite con­fined and dif­fi­cult. For po­si­tion­ing the mag­nets pre­cise­ly and quick­ly, a high ac­cu­ra­cy au­to-tun­ing gird­ers sys­tem com­bined with sur­vey net­work pro­ce­dures were es­tab­lished to ac­com­plish the in­stal­la­tion tasks. The po­si­tion data from the sur­vey net­work will de­fine a basis for the mo­tor­ized gird­er sys­tem to au­to-tune and im­prove the ac­cu­ra­cy. A mock­up of one twen­ty-fourth sec­tion (one cell) had been in­stalled at NSRRC for in­ter­face ex­am­i­na­tion and fur­ther test­ing. In this paper, the pro­ce­dures from the tra­di­tion­al sur­vey net­work to au­to-al­i­ment sys­tem de­sign and al­go­rithm are de­scribed. Mean­while, a pre­lim­i­nary test­ing re­sult is also in­clud­ed.
