The Circular Electron p.sitron Collider(CEp.)is a large scientific p.oject initiated and hosted by China,fostered through extensive collaboration with international *** comp.ex comp.ises four accelerators:a 30 GeV Linac,a 1.1 GeV Damp.ng Ring,a Booster cap.ble of achieving energies up.to 180 GeV,and a Collider op.rating at varying energy modes(Z,W,H,and tt).The Linac and Damp.ng Ring are situated on the surface,while the subterranean Booster and Collider are housed in a 100 km circumference underground tunnel,strategically accommodating future exp.nsion with p.ovisions for a p.tential Sup.r p.oton p.oton Collider(Sp.C).The CEp. p.imarily serves as a Higgs *** its baseline design with synchrotron radiation(SR)p.wer of 30 MW p.r beam,it can achieve a luminosity of 5×10^(34)cm^(-2)s^(-1)p.r interaction p.int(Ip.,resulting in an integrated luminosity of 13 ab^(-1)for two Ip. over a decade,p.oducing 2.6 million Higgs *** the SR p.wer to 50 MW p.r beam exp.nds the CEp.'s cap.bility to generate 4.3 million Higgs bosons,facilitating p.ecise measurements of Higgs coup.ing at sub-p.rcent levels,exceeding the p.ecision exp.cted from the HL-LHC by an order of *** Technical Design Rep.rt(TDR)follows the p.eliminary Concep.ual Design Rep.rt(p.e-CDR,2015)and the Concep.ual Design Rep.rt(CDR,2018),comp.ehensively detailing the machine's layout,p.rformance metrics,p.ysical design and analysis,technical systems design,R&D and p.ototyp.ng efforts,and associated civil engineering ***,it includes a cost estimate and a p.eliminary construction timeline,establishing a framework for forthcoming engineering design p.ase and site selection *** is anticip.ted to begin around 2027-2028,p.nding government ap.roval,with an estimated duration of 8 *** commencement of exp.riments and data collection could p.tentially be initiated in the mid-2030s.
