MOYAA05 | The Status of CEPC | 30 |
|
||
Circular electron-positron collider (CEPC) is a dedi-cated project proposed by China to research the Higgs boson. The collider ring provides e+ e− collision at two interaction points (IP). The luminosity for the Higgs mode at the beam energy of 120GeV is 3*1034 cm-2s-1 at each IP while the synchrotron radiation (SR) power per beam is 30MW. Furthermore, CEPC is compatible with W and Z experiments, for which the beam ener-gies are 80 GeV and 45.5 GeV respectively. The lumi-nosity at the Z mode is higher than 1.7*1035 cm-2s-1 per IP. Top-up operation is available during the data taking of high energy physics. The status of CEPC will be introduced in detail in this paper. | ||

TUYBA04 | Some Issues on Beam-beam Interaction at CEPC | 116 |
|
||
Funding: Project 11775238 supported by NSFC In this paper, the beam-beam study in CEPC CDR is briefly introduced. Some issues related with beam-beam interaction will be emphasized. The bunch lengthening due to impedance and beamstrahlung is simulated in a more self-consistent method. It is found that there exist very narrow stable working point space at W-mode during the CDR design study. We’ll show wider tune scan result. It is found that there exist some disagreement between dynamic aperture and beam lifetime. We try to define the so-called diffusion rate map to explain the cause. Some initial result for different lattice solution is shown. |

WEXBA05 | Machine Detector Interface for CEPC | 217 |
|
||
The Circular Electron Positron Collider (CEPC) is a proposed Higgs factory with center of mass energy of 240 GeV to measure the properties of Higgs boson and test the standard model accurately. Machine Detector Interface (MDI) is the key research area in electron-positron colliders, especially in CEPC, it is one of the criteria to measure the accelerator and detector design performance. In this paper, we will introduce the CEPC superconducting magnets design, solenoid compensation, synchrotron radiation and mask design, detector background, collimator, mechanics assembly etc on, which are the most critical physics problem. | ||
