6. Daniel Schoerling TE-MSC-MNC 6 III. Design Report Rolling direction 2D and 3D field homogeneity optimization was performed. Magnets will be powered in series. Magnetic measurement foreseen on a straight path in the centre of the magnet and results will be compared with simulations. Many more detailed of the magnetic design of this magnet are documented in the design report EDMS 1297334.

11. Daniel Schoerling TE-MSC-MNC 11 IV. Safety Safety Aspects Electricity risks: IP2X, Grounding according to EDMS 1298078 (protection of equipment only). Magnetic field risks: Magnetic fields below 1 T. Water risk: Spraying of water to other equipment cannot be excluded. Overheating and fire risks: thermo-switches, flow-switches, all materials conforming with IS41. Radiation hazards: at least 1 MGy radiation resistant.

12. 12 V. Drawings Functional drawings of assembled yoke, coil and yoke halves are stored in CDD under AD_MBHCB. Yoke will be machined by milling because long ramp- rates are allowed in TL. Ends will be machined at assembled yoke to achieve the required tolerances. No special difficulty is expected during manufacturing. Daniel Schoerling TE-MSC-MNC

13. 13 V. Status & Conclusion Functional specification, design report and engineering specification were prepared and approved. Drawings and technical specification is under approval. Potential companies were selected with a Market Survey and an additional candidate was audited yesterday. We will soon proceed with the price enquiry. Daniel Schoerling TE-MSC-MNC
