Inside the vacuum vessel; the cold mass is supported by six axial tie rods and eight radial tie rods. The axial tie rods are positioned at one end of the cold mass; equispaced around the circumference. They take axial forces; magnetic and seismic. The eight radial tie rods are positioned for each end at 45O from the horizontal; aligned tangentially. They take the vertical and sideways forces; seismic and magnetic. The seismic loads are included considering a sideways force of 0.2g and vertical force of 1.6g. Combined loads gives forces as high as 37 t (compressive) for the axial rods and 25 t for &her adial rods. The cryostat is supported by the iron yoke. through four main support brackets which are fitted to the barrel. A solution was also studied to support the inner detector (50 t) to the iron yoke through the cryostat. In this case eigth subsidiary support brackets were needed because of the seismic load at the inner detector. Fig. 1 shows a part of the designed extemal supporting system;
