| 英文摘要 | In order to reduce the beam impedance and refrigeration power dramatically, we have designed a high temperature superconductor (hts) coated beam screen to screen the cold chamber walls of the super proton-proton collider bending magnets from beam-induced heat loads. it employs an absorber, inspired by the future circular collider studies, to absorb the immense synchrotron radiation power of 12.8 w/memitted from the 37.5 tev proton beams. such a structure has the advantage of decreasing the electron cloud effect and improving the beam vacuum. we have compared the critical magnetic field and current density and accessibility of two potential hts materials for the beam screen, tlba2ca2cu3o9-delta (tl-1223) and yttrium barium copper oxide (ybco) and finally chose ybco for coating. the beam screen is tentatively designed to work at 55-70 k because of the limited development of the ybco material. the thermal analysis with oxygen cooling fluid indicates that the ybco conductor can maintain its superconductivity even if the synchrotron radiation hits the ybco-coated surface and the mechanical analysis shows that the structure has the ability to resist the lorenz force during magnet quenches. published by aip publishing. |
