Presentation Transcript

  1. Coupling Magnet Cryostat Mechanical Structure Design and Manufacture Caoyun, Wangli, Sunsen 2010-12-09 Shanghai Institute of Applied Physics Chinese Academy of Sciences P. R. China

  2. 插入一张总装图 The Overall Structure

  3. Interface with RF cavity Cold mass vessel Cold mass support The gap is 2mm Welding joint RF chamber gussets RF coupler The gap is 4mm Vacuum port 8- M16 bolts support cold mass vessel Cold mass vessel

  4. Vacuum ports Auxiliary port Pirani gauge Auxiliary port pump Hot cathode gauge Auxiliary port Auxiliary port

  5. The welding structure of dis/assemble

  6. Main shield structure： Weld Cu-Al bimetal Disassembly cover The gap between upper and down is 2mm 6mm 4mm G10 insulated shutter The gap is 10mm

  7. The top of shield ： First piece Second piece third piece weld ？ Not a single piece SS bar The hole for cable Demountable access openings weld ？

  8. The support of shield： Joint glued by Epoxy All around weld Spring washers 补偿冷收缩

  9. Thermal joint of shield Thermal joints Local shield

  10. GAP Between the shield and mass Between the shield and vessel Between shield and down He container Between shield and mass support Min. gap

  11. Load cell for cold mass support Spherical washer Load sensor Connect with vacuum vessel support sleeve Connect with cold mass support cold base

  12. 制造工艺考虑 主真空室制造 以中间圆孔为基准加工侧板八孔 加工中间圆孔和侧板基准 真空室周边板焊接 定位支撑筒、点焊 定位支撑筋板、点焊 焊接支撑筒和筋板 以中间圆孔和侧板为基准加工8个支撑筒支撑面、上法兰大平面 加工中间圆孔和侧板基准

  13. Fabrication of thermal shield 与冷质量组装后焊接 三面焊接

  14. 组装工艺考虑： 线圈及冷却管路检漏及低温调试 冷屏 机械中心转移 冷质量及屏 冷质量组件 上真空室制造、检漏 冷却组件焊接、检漏 下真空室制造、检漏 装入拉带、调整冷质量位置、中心转移 装拉紧杆，装箱 运到美国 低温调试 总装组焊

  15. Assembly process

  16. Alignment 将轴线和中分平面数据转移到支座8个点上。 8个转移点 测量内环面和两侧面，求出冷质量轴线和中分平面，建立坐标系。 伸展距离2400

  17. 冷质量机械中心转移 冷质量靶标点 共8点 真空室上靶标座 16点 焊接在真空室外的靶标座

  18. Transport form Beijing to USA. First: enclose this screw bar Second : put the tilted flange on the vessel Third : screw the Spherical nut Pull force Reach USA. Take down this bar and flange Blind flange or vacuum port

  19. Air-ferry？ Max. width :2769 Max. height:3017 ？

  20. MuCool coupling magnet Support design: interface information needed?
