A shield of He-gas-cooled tungsten beads in under consideration. The mass of this shield will be ~ 200 tons, so stress and deformation of the shield are important mechanical issues. Another issue is the intercoil forces in the 20-T magnet system which will be as high as 500 tons, and intercryostat forces which will be as high as 50 ton.. Candidate W beads for use in the shielding: Sketch of the first 3 modules of the target station: Stress and deformations in the outer shield inside the 1st cryostat. σvM in the highest-stressed flange is 540 MPa; δmax is 5.5 mm. Axial magnetic field profile in T (and relative deviations from the ideal profile x 103): Sag in mm of various vessels, as a function of their length. We limit to upstream vessel to 7 m.
