  The Tai­wan Pho­ton Source (TPS) is a low-emit­tance 3-GeV syn­chrotron light source which is in con­struc­tion on the Na­tion­al Syn­chrotron Ra­di­a­tion Re­search Cen­ter (NSRRC) cam­pus. The con­trol sys­tem for the TPS is based upon EPICS frame­work. The stan­dard hard­ware and soft­ware com­po­nents have been de­fined. The pro­to­type of var­i­ous sub­sys­tems is on going. The event based tim­ing sys­tem has been adopt­ed. The power sup­ply con­trol in­ter­face ac­com­pa­nied with orbit feed­back sup­port have also been de­fined. The ma­chine pro­tec­tion sys­tem is in de­sign phase. In­te­gra­tion with the lin­ear ac­cel­er­a­tor sys­tem which are in­stalled and com­mis­sioned at tem­po­rary site for ac­cep­tance test has al­ready been done. The in­ter­face to var­i­ous sys­tems is still on going. The in­fras­truc­tures of high level and low level soft­ware are on going. Progress will be sum­ma­rized in the re­port.

  The Tai­wan Pho­ton Source (TPS) is a lat­est gen­er­a­tion syn­chrotron light source. Strin­gent power sup­ply spec­i­fi­ca­tions should be met to achieve de­sign goals of the TPS. High pre­ci­sion power sup­ply equipped with 20, 18, and 16 bits DAC for the stor­age ring dipole, quadrupole, and sex­tupole are equipped with Eth­er­net in­ter­faces. Con­trol in­ter­face in­clude basic func­tion­al­i­ty and some ad­vanced fea­tures which are use­ful for per­for­mance mon­i­tor­ing and post-mortem di­ag­nos­tics. Power sup­ply of these cat­e­gories can be ac­cessed by EPICS IOCs. The cor­rec­tor power sup­plies' con­trol in­ter­face is a spe­cial­ly de­signed em­bed­ded in­ter­face mod­ule which will be mount­ed on the cor­rec­tor power sup­ply cages to achieve re­quired per­for­mance. The set­ting ref­er­ence of the cor­rec­tor power sup­ply is gen­er­at­ed by 20 bits DAC and read­back is done by 24 bits ADC. The in­ter­face mod­ule has em­bed­ded EPICS IOC for slow con­trol. Fast set­ting ports are also sup­port­ed by the in­ter­nal FPGA for orbit feed­back sup­ports.

  The tim­ing sys­tem of the Tai­wan Pho­ton Source pro­vides syn­chro­niza­tion for elec­tron gun, mod­u­la­tors of linac, pulse mag­net power sup­plies, boost­er power sup­ply ramp, buck­et ad­dress­ing of stor­age ring, di­ag­nos­tic equip­ments, beam­line gat­ing sig­nal for top-up in­jec­tion. The sys­tem is based on an event dis­tri­bu­tion sys­tem that broad­casts the tim­ing events over a optic fiber net­work, and de­codes and pro­cess­es them at the tim­ing event re­ceivers. The sys­tem sup­ports up­link func­tion­al­i­ty which will be used for the fast in­ter­lock sys­tem to dis­tribute sig­nals like beam dump and post-mortem trig­ger with 10 μsec re­sponse time. The hard­ware of the event sys­tem is a new de­sign that is based on 6U Com­pact­P­CI form fac­tor. This paper de­scribes the tech­ni­cal so­lu­tion, the func­tion­al­i­ty of the sys­tem and some ap­pli­ca­tions that are based on the tim­ing sys­tem.
