1. Jigs and procedure for ladder assemblyBelleIInote#8 6th Feb 2012 Yoshiyuki Onuki University of Tokyo

2. Updates • Design of ladder assembly jigs for layer 6 • Forward DSSD(trapezoidal) assembly • Backward DSSD(rectangle) assembly • Booting new lab for the assembly in IPMU. • Equipment • Handling jigs

31. Jig for gluing slant DSSD. goniometer Rotation axis Rotation axis Slant DSSD is chucked here • Edge of slant DSSD will sit on here. • The edge doesn’t move after the rotation. • Precise alignment of slant DSSD can be done in the horizontal plane • on the assembly-bench • This jig can be applied for not only L6 but also L4,L5 ladder assembly.
