The Circular Electron Positron Collider(CEPC)is a large scientific project initiated and hosted by China,fostered through extensive collaboration with international *** com.lex com.rises four accelerators:a 30 GeV Linac,a 1.1 GeV Dam.ing Ring,a Booster capable of achieving energies up to 180 GeV,and a Collider operating at varying energy m.des(Z,W,H,and tt).The Linac and Dam.ing Ring are situated on the surface,while the subterranean Booster and Collider are housed in a 100 km.circum.erence underground tunnel,strategically accom.odating future expansion with provisions for a potential Super Proton Proton Collider(SPPC).The CEPC prim.rily serves as a Higgs *** its baseline design with synchrotron radiation(SR)power of 30 m. per beam.it can achieve a lum.nosity of 5×10^(34)cm.(-2)s^(-1)per interaction point(IP),resulting in an integrated lum.nosity of 13 ab^(-1)for two IPs over a decade,producing 2.6 m.llion Higgs *** the SR power to 50 m. per beam.expands the CEPC's capability to generate 4.3 m.llion Higgs bosons,facilitating precise m.asurem.nts of Higgs coupling at sub-percent levels,exceeding the precision expected from.the HL-LHC by an order of *** Technical Design Report(TDR)follows the Prelim.nary Conceptual Design Report(Pre-CDR,2015)and the Conceptual Design Report(CDR,2018),com.rehensively detailing the m.chine's layout,perform.nce m.trics,physical design and analysis,technical system. design,R&D and prototyping efforts,and associated civil engineering ***,it includes a cost estim.te and a prelim.nary construction tim.line,establishing a fram.work for forthcom.ng engineering design phase and site selection *** is anticipated to begin around 2027-2028,pending governm.nt approval,with an estim.ted duration of 8 *** com.encem.nt of experim.nts and data collection could potentially be initiated in the m.d-2030s.
