12. 12 Magnetic Measurements (1/2) Bent flux-meter development  Magnetic measurement specification discussed with beam optics physicists  need longitudinal distribution of the field  Dipole: –Pre-series: full characterization requires Hall probe 3D mapper (LEP tool to be refurbished) –Series: integrated field mapping with bent flux-meter

13. 13 Magnetic Measurements (2/2)  Quadrupole: –Pre-series: need measurement of field gradient in center + longitudinal profile (3D mapping, but few points and small size) –Series: integrated field harmonics with rotating coil (existing equipment) + fiducialization with stretched wire  H/V correctors: –Pre-series: measurement of field longitudinal profile (3D mapping, small size) + stray field at several locations (magnetic interference) –Series: integrated field harmonics with rotating coil (existing equipment), possibly with sampling (one magnet per batch)  Important workload from this project, can be quite challenging in terms of resources

14. 14  Magnet production –All contracts placed; budget within estimates –Dipoles and quadrupoles: manufacturing design completed; raw materials ordered; tooling manufacture in progress –H/V correctors: manufacturing design in progress  Technical (and schedule) risks –Dipoles: lamination stamping sub-contractor not experienced with accelerator magnets –Quadrupoles: manufacturer unexperienced with laminated yokes –Steerers: quality issues from manufacturer in the past  Magnetic measurements –Scope defined; standard measurements for quadrupoles and steerers –Refurbishment / development of tooling required for dipoles –Important workload of this project will add to the present situation Conclusions
